Mg-SiC (Magnesium-Silicon Carbide) Ceramic Substrates are a type of advanced ceramics that are used in a wide range of high-temperature and high-performance applications, such as in electronics, aerospace, and defense. They are known for their high thermal conductivity, high mechanical strength, high thermal stability, and excellent wear resistance. Mg-SiC ceramic substrates are also often used as a substrate for high-temperature electronic devices, as well as for high-power electronics and heat exchangers. They are often produced by sintering processes, which involve heating a mixture of Mg and SiC powders to form a dense and uniform ceramic material.
