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 …

Wide bandgap power semiconductor devices such as silicon carbide MOSFETs have become an increasingly popular component in electronic circuit designs, as their superior performance over conventional silicon-based power semiconductors make them attractive solutions. MOSFETs consist of three terminals known as source, drain, and gate. Applying positive voltage to the gate creates an electric field which allows current to flow between source and drain to turn on the device. Low On-State Resistance Silicon carbide MOSFETs feature lower on-state resistance than their silicon counterparts, enabling higher switching frequencies and decreasing switching losses, leading to improved system efficiencies in systems such as grid conversion or electric vehicle use. High speed switching in these …
