What raw materials do refractories need
Mainly: refractory clay, silica raw materials, dolomite, magnesite, graphite, pyrophyllite, vermiculite, peridotite, serpentine, chromite, high alumina minerals, zircon and so on; Synthetic refractory raw materials are sintered corundum, synthetic mullite, silicon carbide and so on.
Silicon nitride refractory is a high-grade refractory made of silicon nitride as the main raw material by adding clay, alumina, carbon and other auxiliary raw materials.

Refractory castable formulation
The formulation of refractory castables is usually composed of composite materials, limestone, calcium silicate, graphite, silica sand, alumina, calcium oxide, dust powder, limestone, fly ash, grinding stone and zirconia.
Introduction to refractory materials
A class of inorganic non-metallic materials with a refractoriness not less than 1580℃. Refractoriness refers to the Celsius temperature at which the conical specimen of refractory material can resist the action of high temperature without softening and melting down under the condition of no load. However, only the definition of refractories can not fully describe refractories, 1580℃ is not absolute.
