Hot Pressed Boron Nitride (BN) Ceramic is an advanced ceramic material which can be used up to 2100℃ under atmosphere proction conditions. Boron nitride ceramic is used as good electrical insulatiors because it has high electrical resistivity and can withstand high breakdown voltage (about 3-4 times of alumina ceramic). Hot pressed boron nitride also has good thermal conductivity and low thermal expansion coefficient, will not crack even using in applications where rapid temperature change will occur. Hot pressed boron nitride ceramic can also be used as metal smelting crucibles because it will not react with most molten metals or glasses. Benefiting from its soft hardness, hot pressed boron nitride ceramic can be machined into high accuracy and complicated components easily with common metal processing tools.

Boron nitride plates are manufactured using hexagonal boron nitride (HBN) powder, which is then processed through high-temperature vacuum hot-pressing sintering. These plates have exceptional resistance to high temperatures, extremely stable chemical properties, high electrical insulation properties, and strong resistance to acidic corrosion. The unique quality of boron nitride plates is their non-wetting characteristic with most molten metals, making them suitable for producing ceramic nozzles or crucibles for metal smelting operations. Compared to alumina ceramic or zirconia ceramic, boron nitride plates have low hardness and excellent machinability, which allows for easy machining using standard metal working tools.
