Speaking of ceramics, most people would think that this fragile item is not all like this. If ceramics are added with other additives "boron nitride", etc., super-hard boron nitride ceramics can be produced, which are resistant to high temperature and abrasion. It is a very good heat dissipation material and high-temperature insulating material.
Boron nitride ceramic is a product made of high-quality boron nitride as a raw material. It inherits the characteristics of this special material and exhibits the advantages of high-temperature resistance, non-bonding, corrosion resistance, and good heat dissipation and thermal conductivity. Since it has so many advantages, there are naturally many uses for boron nitride ceramics.
1. Preparation of high-speed cutting tools and probes
Because ceramics and aluminum are not wetted, it can provide comprehensive protection to the surface of materials that are in direct contact with molten aluminum, magnesium, zinc alloys, and their slag, so it can be used to make high-speed cutting tools and drill bits for geological exploration and oil drilling.
2. Made into high temperature, high pressure, insulation, and heat dissipation parts
The shape of boron nitride ceramics can be different, so it can also be made into high temperature, high pressure, insulation, heat dissipation components; or packaging materials to prevent neutron radiation; and special electrolysis and resistance materials that can be used in high-temperature conditions.
3. An ideal high-temperature insulation material
High-temperature insulating materials must meet the basic requirements of high melting point, appropriate high collapse resistance, and chemical compatibility at high temperatures. Boron nitride ceramics are exactly the same. It not only has a high melting point but also has a considerable resistivity at high temperatures. In particular, boron nitride ceramics with hexagonal sheet structure have the advantages of low friction coefficient at high temperature, thermal expansion coefficient similar to tungsten rhenium, and hot briquette can be turned, so it will become an ideal high temperature insulating material.
This is the current use of ceramics in practice, and this diversified use mainly depends on the material with a series of excellent characteristics that can meet the application requirements. With the further improvement of the quality of boron nitride ceramics, its application range will be broader.
