boron nitride ceramics advantages and applications

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, good heat dissipation and thermal conductivity. Since it has so many advantages, there are many uses of boron nitride ceramics.


Because boron nitride ceramic is not wetted with aluminum water, it can provide comprehensive protection for the material surface directly contacting with molten aluminum, magnesium, zinc alloys and their molten slag, so it can be used to make high-speed cutting tools and drill bits for geological exploration and oil drilling.


In addition, boron nitride ceramics can have different shapes, so they can also be made into high temperature, high pressure, insulation and heat dissipation components, or packaging materials to prevent neutron radiation, and special electrolytic and resistance materials that can be used at high temperature.

It is emphasized that high temperature insulation materials must meet the basic requirements of high melting point, proper high collapse resistance and chemical compatibility at high temperature. Boron nitride ceramics are in good agreement. They have not only high melting point but also considerable resistivity at high temperature. In particular, boron nitride ceramics with hexagonal sheet structure have the advantages of low friction coefficient at high temperature, similar thermal expansion coefficient to tungsten Laide, and hot pressing block can be turned, so it will be an ideal high temperature insulation material.


This is the current use of boron nitride ceramics in practice, and this variety of uses mainly depends on the material has a series of excellent characteristics, can meet the application requirements. With the further improvement of the quality of boron nitride ceramics, its application range will be wider.
