High temperature resistance, the melting point of metal silicon is 385050 and the boiling point is 4250. Even after ultra-high temperature arc burning, the weight loss is small and the thermal expansion coefficient is small. The strength of metal silicon increases with the increase of temperature, and the strength doubles at 2000.
Electrical conductivity, thermal conductivity, the electrical conductivity of metal silicon is one hundred times higher than that of ordinary non-metallic minerals. Thermal conductivity exceeds that of steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature, and even at high temperatures, metal silicon acts as an insulator. The reason why metal silicon can conduct electricity is that each carbon atom in metal silicon forms only three covalent bonds with other carbon atoms, and each carbon atom also retains a free electron to transfer charge.
