Silicon carbide - Wikipedia

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in appliions

Quick Answer: Is Silicon Carbide Harder Than Tungsten

True tungsten carbide has very little attraction to a magnet. You should be able to easily pull the magnet away from the carbide. Does silicon carbide dissolve in water? Silicon dioxide has a water solubility of 0.12 g/L, whereas for example silicon carbide is water insoluble. What can break a diamond? That is, it is easily breakable by a hammer.

Silicon Carbide – Abrasive Products, LLC

Silicon Carbide, SiC, is a very sharp, very hard abrasive. It is typically black in color. It is harder than aluminum oxide and is close to the hardness of diamond on the Mohs scale. These characteristics make it an extremely aggressive media. It is often used in blasting appliions where the work piece would be brazed after blasting.
