company news about Characteristics Of Silicon Metal Powder

Silicon metal powder has the following characteristics:

1. High temperature resistance. The melting point of silicon metal is 3850±50℃ and the boiling point is 4250℃. The strength of silicon metal increases with the increase of temperature. At 2000℃, the strength of silicon metal doubles.

2, electrical and thermal conductivity, the electrical conductivity of silicon metal is one hundred times higher than the general non-metallic ore. The thermal conductivity is higher than steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature, and even at high temperature, the metal silicon into an adiabatic. Silicon metal conducts electricity because each carbon atom in silicon metal forms only three covalent bonds with other carbon atoms, and each carbon atom still retains one free electron to transport charge.

3, lubrication, the lubrication performance of silicon metal depends on the size of silicon metal scale, the larger the scale, the smaller the friction coefficient, the better the lubrication performance.
4. Chemical stability. Silicon metal has good chemical stability at room temperature and can resist acid, alkali and organic solvent corrosion.

5, plasticity, silicon metal toughness is good, can be rolled into a very thin sheet.

6, thermal shock resistance, silicon metal at room temperature when used can withstand the drastic change in temperature without destruction, temperature mutation, silicon metal volume change is little, will not produce cracks.
