What is the difference between hexagonal boron nitride and cubic boron nitride

There are four types of boron nitride, hexagonal boron nitride, rhomboid boron nitride, cubic boron nitride and wurtzite boron nitride. It’s easy to confuse hexagonal boron nitride with cubic boron nitride. What’s the difference between hexagonal boron nitride and cubic boron nitride? The difference between hexagonal boron nitride and cubic boron nitride lies in their different physical structures and USES. Boron nitride is a kind of white crystal, stable chemical property, high temperature resistance, melting point up to 3000 degrees Celsius, [...]

Special ceramic materials

Properties of special ceramic materials are determined by two factors. First, the structure of the material, the main bonding properties, the crystal structure. They determine the properties of ceramic materials, such as high temperature resistance, semiconductor and insulation. Secondly, microstructure, including distribution, grain size, shape, pore size distribution, impurities, defects, etc. Ordinary ceramics with clay, feldspar, quartz as raw materials, made by preparation, sintering. This kind of ceramic is hard, no oxidation rust, corrosion resistance, non-conductive, high temperature resistance, [...]

Industrial use of vanadium

Add a few percent of vanadium in steel, can make the elasticity of steel, strength increase, anti – wear and anti – crack very good, both high temperature resistance and anti – cold, no wonder in the automobile, aviation, railway, electronic technology, defense industry and other sectors, everywhere can be seen to trace vanadium. In addition, vanadium oxide has become one of the best catalysts in the chemical industry, including “chemical bread” Mainly used in the manufacture of high-speed cutting [...]
