There is very confusion between silica carbide and diamond. Can anybody help.

Silicon carbide is used as surface finishing material after complete the job and its made up of silicon, carbon.

Sure diamond is most hard substance but the cost and availability limit the use of diamond and therefore silicon carbide is used to the cut the very hard metal.

Silicon is cheaper than diamond thats it is used.

Silicon carbide, also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.

Silicon is less in cost that of diamond and to much hard to cut hard materials. We use diamonds also as cutting tool on cutting edge for more harder materials.

All of you are right that diamond is the hardest material on the earth. But in question he is asking about only Silicon carbide.

Ramesh said:   1 decade ago
Friends, diamond is the hardest natural made substance.

But the silicone carbide is man made that's all. But the world's hardest material is "Lonsdaleite".
