Boron Nitride powder has a white color. This crystal is made of nitrogen atoms as well as boron. With four variants of boron, it contains 43.6% and 56.4% nitrogen.
How does boron Nitride Powder perform?Boron Nitride powder resists chemical corrosion. It is also resistant to acid and water. In hot concentrated alkali, the boron/nitrogen bond can be broken. Boron-nitrogen bonds are broken in hot concentrated alkali. Boron Nitride powder is slightly insoluble when dissolved in hot acid but insoluble when dissolved in water. The properties of powdered boron carbide are generally better than those of carbon materials. The hexagonal boron-nitride has a low friction coefficient and good temperature stability. It also offers high resistance to thermal shock, high strength, high resistance to corrosion, resistance to microwave radiation, and transparent Transparent Infrared.
What preparation methods are used to make boron-nitride powders?Most boron-nitride powder is made with a graphite type structure. This is commonly called white graphite. One is of diamond type. This type can be used to convert graphite to gold, and it’s possible to make diamond type boron nuitride at high temperatures and high pressure. High pressure and high temperature synthesis Wentorf first synthesized cubicBN in 1957. If the temperature exceeds or closes to 1700°C, and the minimum pressure is 11-12GPa (pure hexagonalboron Nitride (HBN), then cubic boron nuitride is created. The use of catalysts is a great way to lower the pressure and temperature transitions. Because of the complexity of its preparation and its high cost, industrial applications are limited. Chemical vapor synthesis Sokolowski was able to use pulsed plasma technology in 1979 to make cubic boron Nitride (CBN) films under low temperatures and pressures. Because the equipment and process are simple, it was easy to develop quickly. Carbothermic Synthesis Technology Boric acid is used to prepare silicon carbide’s surface. It also uses carbon as a reduction agent. Ammonia nitriding is then performed in order to produce boron. It is highly pure and useful for composite material preparation. Sputtering Particle beam sputtering deposited technology produces a mixture of hexagonal and cubic boron nutrides. The method does not contain as many impurities but is more difficult to manage the reaction conditions. This makes it difficult for the product to be controlled. Research on the method holds great promise. Luoyang Trunnano Tech Co., Ltd. is an professional powder company with over 12 year experience in chemical product research and development.
