Lely method - Wikipedia

The silicon carbide near the outer walls of the crucible sublimes and is deposited on a graphite rod near the center of the crucible, which is at a lower temperature. [2] Several modified versions of the Lely method exist, most commonly the silicon carbide is heated from the bottom end rather than the walls of the crucible, and deposited on the lid.

Silicon Carbide Powder Appliion - Nanoshel

Silicon Carbide Powder Appliion: 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.

Subsurface Damage in Polishing Process of Silicon …

Silicon carbide (SiC) ceramic represents a kind of ideal space mirror material by virtue of its high hardness and strength, excellent chemical stability, and good wear resistance [2,3]. However, there remain challenges associated with the inherent properties of SiC, such as its high brittleness and low fracture toughness, which may lead to subsurface microcracks, disloion, deformation, and
