Silicon Carbide Sic Stationary /Rotating Seal Ring for Mechanical Seals

Silicon Carbide (SiC) is one of the most popular high performance tribo-materials, which has been commercially available for more than twenty-five years. Its features include:· Excellent abrasion and wear resistance· Excellent corrosion resistance· Low coefficient of friction· Low coefficient of thermal expansion· High thermal conductivity· Hardness greater than Tungsten CarbideDifferent grades of Silicon Carbide are available as following:· Reaction Bonded Silicon Carbide (RB SiC) - a very economical material which gives excellent wear characteristics, as well as good chemical resistance.· Sintered Silicon Carbide (SSiC) - the absence of free silicon makes it most resistant to chemically-aggressive fluids, and ideal for high temperature applications.· Graphite-Loaded Silicon Carbide - this is a composite of silicon carbide and free graphite. Graphite is added to RB SiC (RB SiC + C) or SSiC (SSiC + C), to improve tribological behavior by enhanced lubricity.  ParameterUnitRB SiCSSiCDensityg/cm33.0 - 3.053.1Free Silicon Content-12%-Crystal Sizeµm8 - 205 - 7HardnessRockwellHRA 90HRA 93Compressive StrengthMPa27003000Flexural StrengthMPa400400Fracture ToughnessMPa4.34.5Elastic ModulusGPa390410Poisson's Ratio-0.150.15Coefficient of Thermal Expansion1 x 10-6 / K4.34.3  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
