Alpha sintered silicon carbide – Mc Nally Institute
Self-sintered silicon carbide carries a slight price premium compared to the reaction bonded version. Although the preferred seal face material, it often is too brittle for some seal face designs. It is one of the most popular materials used in mechanical seal face design and is recommended in high temperature water or hot oil appliions because of its excellent thermal conductivity.

24/9/2015· Additive Manufacturing of SiC Based Ceramics and Ceramic Matrix Composites Silicon carbide (SiC) ceramics and SiC fiber reinforcedSiC ceramic matrix composites (SiCSiC CMCs) offer high payoff as replacements for metals in turbine engine appliions due to their lighter weight, higher temperature capability, and lower cooling requirements.
Silicon carbide - wikidoc
Alpha silicon carbide (α-SiC) is the most commonly encountered polymorph; it is formed at temperatures greater than 2000 C and has a hexagonal crystal structure (similar to Wurtzite). The beta modifiion (β-SiC), with a face-centered cubic crystal structure (similar to diamond and zincblende or sphalerite ), is formed at temperatures below 2000 °C and is shown in the structure at the top
Influence of the alpha/beta-SiC phase transformation on …
The transformation kinetics and microstructural development of liquid phase sintered silicon carbide ceramics (LPS-SiC) are investigated. Complete densifiion is achieved by pressureless and gas pressure sintering in argon and nitrogen atmospheres with Y2O3 and AIN as sintering additives. Studies of the phase transformation from beta to alpha-SiC reveals a dependency on the initial beta
