Silicon carbide, commonly referred to as SSiC, is a hard, chemically inert material used in various applications including sandblasting nozzles and grinding wheels. Silicon Carbide can be machined in either its green or biscuit state; however, for precise tolerances to be reached it must first be sintered and processed using costly diamond grinding processes – once this has been accomplished the parts produced will be dimensionally accurate. High Temperature Resistance Silicon carbide is an inert and chemically hard ceramic material with great temperature-tolerance, remaining strong even at temperatures as high as 1400 degC while being highly resistant to thermal shock and acids/alkalis/molten salts. Since Acheson first invented modern silicon carbide …

Silicon carbide hot surface ignitors have long been the go-to solution for gas furnace ignition. When powered up with 120 volts, they light up red-hot and ignite gas inside their burners – offering quieter and more reliable operation compared to spark ignition systems. Many HVAC construction technicians approach universal SiNi replacement igniters as if they were silicon carbide igniters; however, this is not ideal as their new position within a system differs significantly than before. Advantages Hot surface igniters use an M or fork-shaped ceramic silicon nitride or silicon carbide igniter piece instead of the traditional pilot light to start your furnace. Low voltage electricity passes through it, heating it …
