Sintered Silicon Carbide ( SiC ) Properties and Appliions
Nov 13, 2000· Sintered alpha silicon carbide (SiC) is produced by initially mixing fine (sub-micron) and pure silicon carbide powder with non-oxide sintering aids. The powdered material is formed or compacted by using most of the conventional ceramic forming processes such as die pressing, isostatic pressing and injection moulding.

Nowadays, SiC is industrially manufactured for many appliions included the production of ceramics with outstanding mechanical properties.
Amorphous silicon - Wikipedia
Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs.. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally feature low efficiency, but are one of the most
