graphite and silicon carbide material and design

Silicon Carbide SiC Material Properties

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.

Seal Reliability

2003/1/17The material provides the chemical and abrasive characteristics of silicon carbide with the lubricating qualities and lower heat generation of carbon graphite. It contains approximately 70 percent reaction-bonded silicon carbide (6 percent free silicon) and 30 percent graphite.

Silicon carbide

Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).

Silicon Carbide Coatings

Graphite is also a very porous material and can store compounds in the pores which can interact with the process. To avoid interactions between the graphite surface and seal the porosity of the graphite it is coated with SiC3. In this way the characteristics of

Lightweighted telescope mirrors: Outstanding properties of Silicon Carbide

silicon carbide is deposited on a heated substrate at temperatures higher than 1300 C. As a result, a beta-SiC is obtained. This polytype of SiC is almost fully dense and has very fine columnar grains. Beta-SiC is then deposited on a graphite or SiC bulk

Seal Face Design

Silicon carbide materials have evolved over the years, and they are now more often a two-phase composite, the most popular of which is silicon carbide and graphite. These composites are often referred to as "graphite-loaded" silicon carbide since the graphite is integrated into the silicon carbide structure and not impregnated.
