DURA-SiN
Description
DURA-SiN silicon nitride bead is made from upscale raw material with unique dropping & rolling method. The vacuum kiln gives the beads the exquisite crystalline grain and has outstanding compression strength.
Antioxidation, anticorrosion and wear resistance are its characteristics. It is a ideal option for grinding extreme hard materials such as alumina, boron nitride, silicon nitride, silicon carbide, zirconia and other material.
