Titanium Boride (TiB2) is an extremely hard ceramic which has excellent heat conductivity Boron Product, oxidation stability and wear resistance. Titanium Boride Powder is also a reasonable electrical conductor,so it can be used as a cathode material in aluminium smelting and can be shaped by electrical discharge machining.With respect to chemical stability, TiB2 is more stable in contact with pure iron than tungsten carbide or silicon nitride.
Titanium Boron Diboride is resistant to oxidation in air at temperatures up to 1100 °C,and to hydrochloric and hydrofluoric acids, but reacts with alkalis, nitric acid and sulfuric acid.
Current use of Titanium Boron Powder appears to be limited to specialized Boric Acid Flakes applications in such areas as impact resistant armor, cutting tools, crucibles, neutron absorbers and wear resistant coatings.
TiB2 is extensively used for evaporation boats for vapour coating of Melamine Powder aluminium. It is an attractive material for the aluminium industry as an inoculant to refine the grain size when casting aluminium alloys, because of its wettability by and low solubility in molten aluminium and good electrical conductivity.
Thin films of TiB2 can be used to provide wear and corrosion resistance to a cheap and/or tough substrate.

A "oil shortage" that has spread across the country appears to have already presented signs. Following a one-month shortage of supply of refined oil in Guangdong, Heilongjiang, Qingdao, Kunming and other places have also experienced tight supply of fuel, which is related to the two major oil giants and the country. The department sounded the alarm.
Heilongjiang: Private oil station is free of oil
Zhao Youshan, president of the Heilongjiang Petroleum Industry Association, told the reporter that the retail price of the 93rd gasoline market, which is mainly used in Heilongjiang Province, is 4.37 yuan/liter. This price has continued for a month, and there is still a possibility of rising.
In Heilongjiang gas station, the current oil price is not uniform, and the original private gas stations that originally depended on purchases from PetroChina gas stations and retailed are now basically free of oil.
Zhao Youshan revealed that in Heilongjiang, queues for refueling are appearing in many places, but “there is still no time to add oilâ€.
He said that compared with Liaoning, Jilin and Heilongjiang, due to its remote location in the northeast, the supply of refined oil is relatively inconvenient. In addition, Russia’s estimated oil supply for exports to China this year is reduced by 30%, resulting in some “starved†petrochemicals in Heilongjiang Province. The company added "hunger hunger."
Another important reason is that Heilongjiang began to promote ethanol gasoline in the province last October. The current market coverage rate has reached two-thirds. Although the gas stations have not undergone scale transformation, the refineries were directly required to stop production of refined oil and aggravate supply. Oil tension.
Qingdao: 50% petrol station cannot refuel properly
Some petrol varieties in Shandong have stopped supplying at some petrol stations. The overall supply tends to be tight, but there has been no queuing oil purchase.
The relevant person in charge of the Economic Operation Bureau of the Provincial Economic and Trade Commission responsible for the operation of coal, electricity, and oil in Shandong Province told this reporter that Shandong’s fuel supply was still relatively normal. Although it was tense, it did not appear that some cities in the south could not add oil.
Yesterday (16th) afternoon, the reporter learned at the PetroChina gas station at Qineng Road in Jinan City that the 90th gasoline had stopped supplying it a week ago. Many of the motorcycles originally fuelled with the 90th gasoline were now forced to use 93rd gasoline. However, there was no line up at this gas station.
Afterwards, the reporter went to a designated gas station called Anda in the Shandong provincial government office. The daily supply of this gas station is about 10 tons. The station staff said that No. 90 gasoline had been stopped supply two days ago, and diesel has been targeted for supply as early as a month ago. The use of cash plus diesel is no longer possible, and diesel is now only available to contract units. Other types of fuel, such as 93# gasoline, 97# gasoline, etc., although gas stations are more nervous than before, they can basically guarantee supply.
Compared with Jinan, the situation in Qingdao is relatively tight. Our reporter learned from local media reporters that many gas stations in Qingdao have limited fuel supply. Gas stations that cannot be refueled are estimated to have 50%. Many private gas stations can only provide fuel to fixed customers, and some gas stations only supply 97. Oil.
Yunnan: No. 90 and No. 93 oil shortage
Fuel shortage! This has become the most distressing problem for most gas stations in the country. Yunnan, which is far from the southwest, is also facing this problem.
“We are all closed for two days! There is no oil, the business can not do it.†The head of the gas station in the northern suburbs of Kunming Wuhua complained to reporters. According to the person in charge, about 70 to 80 percent of gas stations in Kunming have no access to gasoline No. 90 and No. 93. CNPC and Sinopec have no oil supply. Taxes and rents have to be paid. They are now hot. Ant on the pot.
A gas station employee in Xishan District, Kunming, told the reporter that No. 90 gasoline has been deprived of oil for half a month. This does not seem too bad. In Anning City near Kunming, at a gas station owned by Sinopec, No. 93 gasoline has been out of stock for more than a month.
The reporter learned that in Hekou County, which is just across the river from Vietnam, the situation is not optimistic. Just last Wednesday, 93 and 97 gasoline in the area were warned that the only available gasoline No. 90 was limited to 10 liters of oil per vehicle.
An internal employee of Sinopec Yunnan Branch also told reporters honestly that the supply of gasoline No.90 and No.93 has been intermittent and insignificant since the last three to four months. "For three or four months, No. 90 oil has only received more than 20 train wagons." It seems that the fuel really has to sound a red alarm. However, this data has not been confirmed by the authorities.
Nanjing: "Oil" to "Gas" Come Back
The rise in the price of gasoline and the intensive use of fuel have brought Nanjing “oil†to “gas†again on the agenda, and buses have become “first moversâ€.
Since August, the price of Nanjing No. 90 gasoline has increased from 3.9 yuan per litre in July to 4.2 yuan per litre, and many taxi drivers have changed their “oil†to “gasâ€.
Since the completion of Jiangsu's first natural gas vehicle refueling station in the Tianbao Driving School in the southwestern suburbs of the city in late April, the Nanjing fuel market has seen a trend of “three pillars†of gasoline, liquefied gas, and natural gas. However, there is still a bottleneck in the development of large-scale popularization of “gas†and “oilâ€.
At present, Nanjing has only one natural gas filling station. Li Xunkang, deputy general manager of Nanjing Bus Corporation, said that the company is currently coordinating with China Resources and other units and intends to build sites for gas refueling at Shazhou, Fengtai South Road, Maqun, Communist Youth League Road, Daqiao South Road and Taishan New Village. The station, after completion, can meet the refueling requirements of 800 to 900 natural gas buses.
It is reported that Zhongbei Bus Company also plans to transform the original Hongshan Liquefied Gas Station into a natural gas filling station. Next month, 10 natural gas buses will take the lead. If the overall benefit after the test is good, North China will promote it.
At present, Nanjing’s buses have become the most likely pioneers of “ventilationâ€. However, to promote it to the community, the distribution point is still no small resistance. According to sources at the Nanjing Tianbao Natural Gas Refueling Station, since the natural gas at the gas station needs to be treated with high pressure, the conditions for the gas station are very harsh. It requires no residents within 500 meters of the gas station to live. In addition, the technical requirements for the operator are also high.
The high cost of car modification is also a problem. Although the theoretical calculations can basically be recovered within six months, it is necessary to convince the bus companies and taxi drivers who purchase cars at their own expense to spend 5,000 to 8,000 yuan at a time. At the same time, because the vehicles that use gas are all modified, there are only one qualified natural gas vehicle conversion manufacturer in Nanjing and there is a certain amount of trouble to repair it.
Taking all of these costs into account, natural gas is not an everyday matter when it comes to entering the market based on price advantages.
