Why silicon carbide is use in cutting tools?
Silicon carbide and silicon carbide ceramics are black, high-strength materials with higher hardness and better thermal shock resistance than alumina. They have superior properties for power devices and are predicted to revolutionize the power electronics industry. These hard ceramics consist of grains of silicon carbide which can be bonded together by sintering.
How hard is Jasper the gem on the moh hardness scale?
Jasper is a hardness of 7 on Mohs scale. Jasper is a type of Chalcedony, a variety of quartz (silicon dioxide) often with some iron and aluminum. Jasper gets it's colors from iron oxides.
Mineral composition of quartz?
SiO2 Please be a bit more precise. The composition of quartz is SiO2 which means that two atoms of oxygen share one atom of silicon. It can be described as "Silicon di-oxide," and as a result it forms long hexagonal crystals which may be surmounted with a six sided pyramid. On the Mhos scale of hardness it has a hardness of 7. Varieties of quartz include flint, amethyst, rose quartz etc. It also forms a massive variety which is often seen in metamorphic rocks, as a crystal in granites. In pure form it resembles clear glass. It has a conchoidal fracture.
