DESCRIPTION
Silicon metal powder is commonly used as a raw material in the production of refractory materials, which are materials that can withstand high temperatures and harsh environments. The properties of silicon metal powder make it an ideal material for refractory applications due to its high melting point, good thermal conductivity, and excellent resistance to thermal shock.
In refractory applications, silicon metal powder is typically combined with other materials, such as alumina, magnesia, and zirconia, to produce specialized refractory materials that are optimized for specific high-temperature applications. The addition of silicon metal powder to these materials can improve their mechanical and physical properties, such as thermal shock resistance, strength, and durability.
The production of silicon metal powder for refractory applications typically involves the reduction of high-purity silica with carbon in an electric arc furnace, followed by the grinding and milling of the resulting silicon metal to produce a fine powder with a controlled particle size distribution. The particle size and distribution of the powder can be further refined through various milling and classification techniques to produce a powder that is optimized for refractory applications.
