Overview of Boron Nitride Ceramics
Boron nitride ceramics, also known as "white graphite," are characterized by their machinability, custom design capabilities, excellent heat resistance, low thermal expansion, superior thermal shock resistance, high electrical insulation, non-wettability by molten metals and glass, and excellent corrosion resistance.

BMATS® Solid Boron Nitride
This unique material from the company offers superior properties compared to conventional ceramics, capable of withstanding temperatures over 2000°C. Its microstructure resembles graphite, hence the name "white graphite."
