Description:
The high density black silicon carbide fused by heating high puritysilicon sand used in refractory and ceramic industry.The highdensity black silicon carbide fused by heating high purity siliconsand and carbon in a big
electrode furnace at above 2500 0C. With high density, big crystal,and good purity, it is widely used
in abrasive, refractory and ceramic industry.
CF-16 is ablack, friable, medium bulk density silicon carbide abrasive grain.To get this kind of
grains, we specially process the ingots, separate the magneticmaterial, and sieve the grains
carefully to get a complete range of grit sizes.
Applications:
CF-16 is used in making vitrified bonded grinding wheels, resignbonded grinding wheels. As loose
grains, it is widely used for pressure blasting, surface finish andother general industrial
applications.
