Silicon Carbide SiC Material Properties - Accuratus

Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.

Investigation of Amorphous Silicon-Carbon Films …

The silicon composition in the films determined by XPS varies from 0 to 61 at.%. The Raman results show that at low silicon composition, the G position of C-C bond shifts to a low wavenuer, that demonstrates the silicon atom predominantly substitutes for the carbon atom.

In-Situ and Porous Composites

Alumina-silicon carbide composites have been synthesized in-situ in a microwave reactor by two different methods, namely, polymer infiltration and pyrolysis ( PIP) and direct pyrolysis of a alumina-polymer mixture (DPP). The percentage of silicon carbide in

Suspension Plasma Spraying of Sub-micron Silicon …

Thermal spraying of silicon carbide (SiC) material is a challenging task since SiC tends to decompose during atmospheric spraying process. The addition of metal or ceramic binders is necessary to facilitate the bonding of SiC particles, allowing SiC composite coating to be deposited. In the conventional procedures, the binders are added through mechanical mixing of powder constituents, making
