sintered vs reaction bonded silicon carbide singapore
Face Materials | Types of Mechanical Seal Faces
The most common is reaction-bonded silicon carbide. In Chemical appliions however, Alpha Sintered Silicon Carbide may be recommended. Alpha Sintered Silicon carbide does however sace the Pressure Velocity ratios due to the lack of un-reacted free carbon.
The Trouble With Silicon Carbide | Pumps & Systems
Traditionally, pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s, OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.
