Olivine

Olivine is a naturally occurring mineral that belongs to the orthosilicate group. It is typically found in igneous and metamorphic rocks, and has a chemical formula of (Mg, Fe)2SiO4. Olivine is a green to brownish-green color and has a glassy or granular appearance.

Olivine is widely used as a refractory material due to its high melting point, high thermal conductivity, and excellent resistance to thermal shock. It is commonly used as a raw material for making refractory bricks, furnace linings, and other high-temperature applications. Olivine is also used as a foundry sand and as a flux in the steel and glass industries.

Olivine is available in a range of grades, each with its own specific chemical and physical properties. The most common grades have a high magnesium content, typically ranging from 50% to 80%, with the remainder consisting of iron and other impurities. The particle size and density of olivine can also be tailored to meet specific application requirements.

Overall, olivine is a versatile and high-performance mineral that is essential for many high-temperature industrial processes. Its excellent resistance to thermal shock, high melting point, and high thermal conductivity make it a preferred choice for use in harsh environments where other materials may fail.
