High temperature resistant boron nitride ceramics

Boron nitride ceramic is a kind of high-performance ceramic material, which has been widely used in many fields due to its excellent physical and chemical properties.
Boron nitride ceramic is an advanced ceramic material composed of boron and nitrogen. Its crystal structure is similar to that of graphite and has a hexagonal crystal structure. It is famous for its high temperature resistance, thermal conductivity, electrical insulation, chemical stability and self-lubrication, and is known as the “King of Ceramics”.

Application
Boron nitride ceramics are widely used in the following fields due to their unique properties:
(1) Aerospace
It is used in the manufacture of high-temperature materials, spacecraft external coatings, thermal insulation materials, etc. Due to its excellent high temperature resistance and lightweight characteristics, it can significantly reduce the weight of spacecraft.
(2) Military industry
As an armor material, missile component, etc., it has extremely high hardness and corrosion resistance, and can withstand the impact and high temperature in extreme environments.
(3) Chemical industry
It performs well in corrosive media and is suitable for corrosion-resistant components in chemical equipment, such as reactor linings, pipelines, etc.
(4) Electronics and optoelectronics
It is used for the preparation of high-performance lasers, optical devices, and heat dissipation insulation parts, and can meet the needs of precision instruments due to its good thermal conductivity and electrical insulation.
(5) Semiconductor and metallurgy
Manufacturing semiconductor melting crucibles, thermocouple sleeves, glass forming molds, etc. can maintain stability and chemical inertness at high temperatures.
(6) Other fields
As a lubricant instead of graphite, it is used in high-temperature bearings, seals, etc. It performs well in high-temperature and corrosive environments due to its self-lubricating properties.

Custom description
Boron nitride ceramics can be customized according to different application requirements to meet the performance requirements of specific scenarios. The following are common customization directions:
(1) Shape and size
Through cold isostatic pressing and two-way hot pressing sintering technology, it can be processed into complex shapes and high-precision parts, such as crucibles, molds, casings, etc.
(2) Density and porosity
Adjust the density and porosity of the material to optimize thermal conductivity, mechanical strength, and thermal shock resistance, suitable for different operating conditions.
(3) Surface treatment
We provide precision grinding and polishing processes to ensure surface smoothness and meet the needs of optical devices or precision instruments.
(4) Compound modification
By adding other materials (such as ceramics or metals) for composite modification, the strength, corrosion resistance or electrical insulation properties of the material can be further improved.
(5) High temperature resistance and oxidation resistance
For high temperature or oxidizing environments, the anti-oxidation coating of the material can be optimized or a special sintering process can be used to increase the service life.
