Mohs scale of mineral hardness : definition of Mohs …

The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created in 1812 by the German geologist and mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science. [1]

Silicon carbide is – after diamond and boron carbide – the third-hardest mineral in the world. Chemically, silicon carbide is extremely resistant and able to withstand the strongest alkalis and acids. In addition to being used as a blasting medium and abrasive, silicon

Mohs'' hardness scale - CAMEO

1/5/2016· An empirical scale used to approximate the hardness of minerals. The scale, developed by Friedrich Mohs, is based on the ability of one material to scratch another. The Mohs'' hardness scale originally ranged from 1 (soft) to 10 (hard) but has recently been expanded to 15 by Ridgeway to include synthetic abrasives.

Tungsten carbide - Wikipedia

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery , cutting tools , abrasives , armor-piercing shells and jewellery .
