Refractory

A refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures.[1] Refractories are polycrystalline, polyphase, inorganic, nonmetallic, porous, and heterogeneous. They are typically composed of oxides or non oxides like carbides
