Silicon carbide - Wikipedia
Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive..
Aluminum Oxide vs Silicon Carbide Sandpaper | Uneeda
Silicon carbide is a sharper and harder grain compared to aluminum oxide, but silicon carbide is less durable because it is brittle and has a more narrow shape that wears down at an increased rate. Due to its razor-sharp grains, silicon carbide will have no problem easily …

etch rate - definition - English
The method further includes thermally treating the inorganic anti-reflective coating material layer formed thereon such that the thermally treated anti-reflective coating material layer then has an associated second etch rate less than the first etch rate when exposed to the etchant, e.g. the second etch rate is less than 16 Å/minute, the second etch rate is less than 20 % of the first etch
WET ETCHING OF SILICON NITRIDE
WET ETCHING OF SILICON NITRIDE Thin films made of amorphous silicon nitride (Si3N4) are usually deposited by chemical vapour deposition from silane (SiH4) and ammonia (NH3). Since they act as a barrier for water and sodium, they have a major role as passivation layers in microchip fabriion.
