-Moissanite originally referred to a rare mineral discovered by Henri Moissan having a chemical formula SiC and various crystalline polymorphs. Earlier this material had been synthesized in the laboratory and named silicon carbide.
Moissanite has many applications, aside from its traditional use in jewelry as a gem of its own and as a diamond simulant. Because of its hardness, it is useful for high-pressure experiments (e.g., using diamond anvil cell) competing there with diamond.Large diamonds, used for anvils, are prohibitively expensive. Therefore for large-volume experiments, much cheaper synthetic moissanite is a more realistic choice. Synthetic moissanite is also interesting for electronic and thermal applications because its thermal conductivity is similar to that of diamonds. High power SiC electronic devices are expected to play an enabling and vital role in the design of protection circuits used for motors, actuators, and energy storage or pulse power systems.- wiki
