Silicon nitride protection tube

Refractory products are inorganic non-metallic materials that can maintain stable performance under high temperature conditions, and are widely used in construction, metallurgy, petrochemical, aerospace and other industries.
Refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580 ℃, which are mainly used for structural materials of thermal equipment such as high-temperature furnaces, as well as materials of industrial high-temperature containers and components, and can withstand corresponding physical and chemical changes and mechanical effects.
