The silicon carbide which is used as raw material for the matrix layer may be admixed with a sintering aid such as boron carbide and a binding agent, e.g. phenolic resin, after which it is granulated, e.g. by spray drying, to obtain a granulated powder of prescribed
By materials - (주)맥테크
Silicon carbide is an artificial mineral with a strong covalent bonding. It is superior to alumina and silicon nitride in hardness. And it is good in abrasion-resistance, especially in a stick-slip condition. It maintains mechanical strength at a high temperature.
SiC Foundry Business Emerges - Semiconductor Engineering
It starts with silicon and carbon materials, which are inserted in a crucible. In the crucible, a boule is formed and then sliced into SiC substrates. “There are challenges associated with SiC as it has proved difficult to handle, grind and saw, compared to silicon,” said Rich Rice, senior vice president of business development at ASE.
