Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”

Silicon - Thermal Expansion Coefficient. Linear thermal expansion coefficient of Silicon is 2.6 µm/(m·K). Thermal expansion is generally the tendency of matter to change its dimensions in response to a change in temperature. Beryllium is a chemical element with atomic nuer 4 which means there are 4 protons and 4 electrons in the atomic structure.
