Carbides and carbide materials have excellent wear resistance and high hot hardness. They are sometimes referred to as hardmetals. Applications include wear parts and tooling, chemical and material processing, building and construction, and walls and roofing.Carbides are also used in high voltage (HV), radio frequency, and microwave applications.
Carbide, any of a class of chemical compounds in which carbon is combined with a metallic or semimetallic element. Calcium carbide is important chiefly as a source of acetylene and other chemicals, whereas the carbides of silicon, tungsten, and several other elements are valued for their physical hardness, strength, and resistance to chemical attack even at very high temperatures.

Calcium carbide is used in carbide lamps. Water dripping on carbide produces acetylene gas, which burns and produces light. While these lamps gave steadier and brighter light than candles, they were dangerous in coal mines, where flammable methane gas made them a serious hazard.
calcium carbide hardness; calcium carbide hardness. Hard water - Wikipedia, the free encyclopedia. Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of calcium and magnesium-containing minerals such as limestone, chalk and dolomite. ... Calcium carbide ...
The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.
Silicon Carbide is the only chemical compound of carbon and silicon. It was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years.
Silicon carbide ceramics is made by high quality sic fine powder,firing several wearproof,acid- resisting and high temperature resistance parts. Filling up material for high way and airport runway to make road surface skidding resistance and wear meanwhile improving using age.
