What solvents can I use to dissolve Silicon carbide, Product 357391? Unfortunately, Sigma-Aldrich does not test the solubility of this material. Fundamentally, Silicon carbide (SiC) is insoluble in water. However, according to Lange''s Handbook of Chemistry (16th

sharpening carbide toolbits - The Home Machinist!

31/1/2004· Even cast iron should be ground with silicon carbide. Steel has the ability to dissolve silicon at high temperatures, so the net effect is for the grinding wheel to dull immediately. While aluminum oxide is much softer, it does not dissolve into steel in the same manner, thus it displays a much longer cutting ability.
