Hot-Press Boron Nitride BN Amorphous Strips Nozzles
Boron nitride belongs to the hexagonal system. Its structure is similar to graphite, and their properties are also similar. Therefore, it is also called " white graphite". It has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dessipating material and high temperature insulatiing material. Mohs Hardness 2 can be processed into various shaped parts.
Performance
- The optimized formula and unique process make it highly resistance to thermal shock and high-temperature creep. Maximum using temperture 1700℃.
- Low thermal expansion coefficient, no cracking or deformation during use.
- Strong erosion resistance, wear resistance and metal corrosion resistance. Long service life.
- Good raw materials, process control, product stability.
