is it possible for graphite and silicon carbide is grit
Graphene - Wikipedia
Graphene / ˈ ɡ r æ f iː n / is an allotrope of carbon consisting of a single layer of atoms arranged in two-dimensional honeyco lattice. The name is a portmanteau of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.
Carbide | chemical compound | Britannica
Carbide, any of a class of chemical compounds in which carbon is coined 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.
The Ins And Outs Of Silicon Carbide
You can make a MOSFET in silicon and you can make a MOSFET in silicon carbide. MOSFETs in silicon are very common in the low-voltage region, from 10 volts up to about 300 volts. Above 300 volts, the resistance of a silicon MOSFET gets very very high and it makes the MOSFET unattractive.

14/5/2019· There are not a lot of big step-changes in solar technology, but silicon carbide (SiC) could be one of these. The material holds promise for inverters, by allowing for smaller chips with greater power density as well offering a greater switching frequency, meaning fewer of the “passive elements” that make inverters big, bulky and more expensive.

A silicon carbide (SiC) coating is effective in developing the oxidation resistance and the wear resistance of graphite materials and C/C composites, because silicon carbide has good oxidation wear resistance and high hardness.
Polishing Glass How-to and Tips
An easy way to grind out the scratches is to use silicon carbide sandpaper (the black sandpaper available at hardware stores or auto body shop supply houses) with water as a lubricant. After grinding, carefully clean off the area you ground with water and clean off your tools before going to the next finer grit.
