How to make hexagonal boron nitride powder

Boron nitride is a new ceramic material with excellent properties and great development potential. Hexagonal boron nitride (h-bn) is an isomer of boron nitride. The structure of hexagonal boron nitride is similar to that of graphite, with a hexagonal layered structure, soft texture, strong workability, and white color, commonly known as “white stone ink”. The following to introduce the commonly used method of making powder of hexagonal boron nitride. 1. Chemical vapor deposition (CVD) method. H-bn powder is generally prepared by [...]

Technology and principle of industrial extraction of vanadium pentoxide

The main raw materials for industrial extraction of vanadium pentoxide are vanadite-containing coal mines and vanadium titanomagnetite. The grade of vanadium pentoxide in vanadite-containing coal mines is generally 0.5-1.5%, and vanadium titanomagnetite is vanadium pentoxide Grade is generally between 1.0 and 5.0%. Mineral decomposition There are two kinds of decomposition methods of vanadium ore, the first is sintering method, the pulverized ore powder mixed with soda ash or sodium salt and sintered at high temperature, so that the low-priced vanadium oxidized and [...]

Boron nitride is a kind of white crystal, stable chemical property, high temperature resistance, melting point up to 3000 degrees Celsius, [...]

Research on flame retardant nano magnesium hydroxide process

China’s plastic flame retardant material is mainly based on decabromodiphenyl ether, but decabromodiphenyl ether in combustion will produce toxic carcinogenic polybrominated dibenzofuran and other substances, and make it some countries to resist the use of. Therefore, flame-retardant materials also develop towards the direction of high efficiency, low toxicity and low smoke. It is necessary to develop nontoxic flame retardant with excellent performance. Inorganic materials used as flame retardants include Mg(OH)2, AL(OH)3, Sb2O3, etc. These inorganic flame retardants not only [...]
