Boron Nitride :
Boron Nitride Ceramic is one of industrial ceramic materials, its hardness and mechanical strength is not as high as other Al2O3, ZrO2, Si34,
SiC and AlN ceramics, so it is not suitable for mechanical applications. Its most famous features are in thermal and electrical
applications and most applied as heat resistant parts or electrical insulators for various fields.

Feature
●High temperature resistance (especially in inert gas or vacuum, up to around 2000℃)
●Good electrical insulation (breakdown strength is 4 times of Alumina Ceramics)●Good chemical stability and no reaction with most
molten metals like Cu, Stainless Steel, Fe, Sn, Zn and Sb etc.
●Good machinability, can be easily machined with normal metal tools
