Comparison of the heating rate of powdered tungsten carbide- cobalt (WC-Co) sample (microwave power 200W) (Cheng et al. 2001) 4. Examples of microwave synthesis The nature of the minerals as they exist at atmospheric pressure represents only a part of their real nature.
On the other hand, the metalloid silicon forms silicon carbide, Sic, a carbide with important industrial and practical uses, both as an abrasive and as a refractory. The major appliions of metallic carbides are as cutting materials (abrasives) or for resistance to high temperatures (refractories); however, a nuer of metals form compounds with carbon having simple formulas, such as CaC2
A harder, non-flexible rubber matrix is often used for moulded silicon carbide discs. Synthetic or natural abrasives may be used including. - Silicon carbide (carborundum) - Aluminium oxide - Garnet - Quartz - Pumice - Cuttlebone Cutting mechanism: For cutting it is necessary to apply sufficient pressure to make the cutting edge of a blade or abrasive particle dig into the surface.

Boiling chips are an old, practical invention rather than an impervious ideal tool, so it is smart to understand why your boiling-chip substance is OK for your appliion. If you are really trying to stay pure, there are at least 4 kinds of substances that boiling chips
Silicon Carbide, SiC Silicon carbide SiC is among the hardest known substances. In industry it is widely used as an abrasive material under the name carborundum. It is prepared by heating to about 3000K, a mixture of five parts silica and three parts powdered coke along with some saw dust.
