Product Description

It's so exciting to present this news that a new material member named BSN joined Solid Boron Nitride family. BSN is a composite material, it's made from BN and Silicon Nitride. It's with very good mechanical strength and wear resistance. BSN is often used as nozzle, crucible and stir rods due to its high performance. The working life is much longer compared with other composite BN materials.

 

Features:
• Best wear resistance in Solid BN family
• Best mechanical strength in Solid BN family
• Good thermal resistance
• Low thermal expansion
• Good thermal shock resistance
• High electrical insulation
• Non wet to molten metal and glass
• Good corrosion resistance
