China Boron Nitride Ceramics
Boron nitride ceramic is a kind of product made of high-quality boron nitride as raw material. It inherits the characteristics of this special material, showing the advantages of high temperature resistance, non-bonding, corrosion resistance, heat dissipation and thermal conductivity. Since it has so many advantages, the use of boron nitride ceramics is also a lot of nature.
Boron nitride ceramics can be used to make high-speed cutting tools and drill bits for geological exploration and oil drilling, because boron nitride ceramics are not wettable with aluminum water and provide comprehensive protection to material surfaces in direct contact with molten aluminum, magnesium, zinc alloys and their melting slags.
In addition, the shape of boron nitride ceramics can be different, so it can also be made into high temperature, high pressure, insulation, heat dissipation parts; Or packaging materials to protect against neutron radiation; And special electrolysis and resistance materials that can be used at high temperatures.
It is emphasized that high temperature insulating materials must meet the basic requirements of high melting point, appropriate high collapse resistance and chemical compatibility at high temperature. Boron nitride ceramics fit the bill, having both a high melting point and considerable resistivity at high temperatures. Especially the hexagonal sheet structure of boron nitride ceramics has the advantages of low friction coefficient at high temperature, thermal expansion coefficient similar to tungsten, hot press block can be turned, so it will become an ideal high temperature insulating material.
