Silicon Carbides (SiC) exhibit characteristically high hardness, wear resistance, corrosion resistance, and strength — even at high temperatures. CoorsTek has engineered a variety of silicon carbide processes and compositions which deliver properties and features

Low-Pressure Silver Sintering of Automobile Power …

To improve the efficiency of power modules in environmentally friendly vehicles, silicon-carbide (SiC) chips and silicon-nitride (Si3N4) active metal-brazed (A) substrates were bonded by low-pressure silver (Ag) sintering at 220°C and 1 MPa using Ag paste. The initial bond strength of the sintered joint was 35.7 MPa, and the void content and bonding-layer thickness of

Reaction Bonded Silicon Carbide – Mc Nally Institute

Reaction bonded silicon carbide is produced by adding molten silicon to a mixture of silicon carbide and carbon. A reaction between the silicon and carbon bonds the structure while the excess silicon metal fills the majority of the pits left in the resultant material.

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.

Porous Silicon Carbide Sintered Substrates for High …

Silicon carbide (SiC) porous substrates are prepared by pressureless sintering of SiC powders under an inert atmosphere of argon. The porous SiC substrates were characterized by measuring their porosity, pore size distribution, surface characteristics, and structure. Their transport characteristics were investigated using N2 and He as the test gases. Three different starting powders and four
