Silicon Nitride BeadsNanorSiN

Description:

Silicon nitride beads NanorSiN are forming in unique extrusion

processing from high grade silicon nitride powder and are sintered in the

thermocompression kiln. The exquisite crystalline grain give the bead

outstanding crushing strength, antioxidation, corrosion resisting and wear

resistance. It is a innovative ceramic media for grinding extreme hard

materials such as alumina, boron nitride, silicon carbide and zirconia.       

Features:

Relative to the zirconia beads, it has higher hardness for grinding the

hard materials; Compared to alumina beads, higher toughness means less

broken. The disadvantage is low density which will decrease grinding

efficiency.
