Overview of Silicon Carbide Seal. Silicon Carbide - Is a bluish-black material created by fusing silica and coke. It is in the same family as Ceramic (due to the Silica), but has much better lubriion qualities and is harder. The most common silicon carbide used in a mechanical seal is reaction-bonded silicon carbide.

07/06/2016· Newark, DEL. - June 07, 2016. Dow Electronic Materials, a business unit of The Dow Chemical Company (NYSE: DOW), today launched its Optiplane™ slurry platform for chemical mechanical planarization (CMP). The Optiplane™ slurry family was developed to satisfy customer demand for advanced slurries that can meet defect reduction requirements
The substance also exhibits crystallizing properties, which regularly cause problems during the technical processing. Sulfur is in a liquid state in a temperature range between +120 °C … +160 °C (+248 °F … 320 °F). While pumping liquid sulfur, continuous minimal leakage in the area of the shaft seal frequently causes problems.

Heat checking can also occur when the seal chaer is full of gas — the seal starts up dry, gets very hot and then is suddenly hit with liquid. Hard faces such as Stellite, alumina (ceramic) and tungsten carbide are subject to heat checking. Silicon carbide faces can show heat checking but this is somewhat rare.
