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. Refractories are inorganic, nonmetallic, porous, and heterogeneous. They are typically composed of oxides or non-oxides like carbides, nitrides etc. of the following materials: silicon, aluminium, magnesium, calcium, and zirconium.
MAGMA provide almost all the refractory main minerals like CALCINDED BAUXITE, SINTEREND MULLITE, BFA, WFA, SIC, B4C, TABULAR ALUMINA ETC.. which act as the main matrix and aggregate both in shaped and unshaped refractory materials.
