Refractory Raw Materials

White tabular alumina is the aggregate of choice in unshaped and shaped high performance refractories.

White corundum is a very high-quality refractory raw material with the characteristics of high hardness, high strength, heat resistance and chemical stability. It has a wide range of applications and

Brown corundum, widely used in the field of refractory raw materials, is a high-quality quartz sand product with high hardness, high melting point, corrosion resistance and flame retardancy. As an

The purity of refractory calcined alumina powder is as high as 99.99% or more. Due to its excellent performance, it is widely used in the field of refractory materials, such as casting, smelting,

refractory high-alumina bauxite is an excellent refractory material with high heat resistance, compressive strength and chemical stability. It is widely used in steel, cement, glass, chemical and

Magnesia is one of the raw materials for refractories. Also known as magnesia refractory raw materials, it refers to raw materials with MgO as the main component and periclase as the main crystal

Magnesia (magnesite clinker) is one of the most important raw materials for refractory materials. It is used to manufacture various magnesia bricks, magnesia-alumina bricks, ramming materials,

High-temperature calcined alumina powder is made of industrial aluminum hydroxide or industrial alumina as raw material, and is calcined at an appropriate temperature to form a stable α-type alumina

Calcined bauxite is a high-alumina (80--90%), durable mineral produced by heating raw bauxite to 1600--1800℃ in kilns to remove moisture and impurities. It is primarily used for its high

With the continuous improvement to performance requirements of refractory materials, the proportion of corundum used in refractory materials is getting higher and higher. Corundum for refractories

Flint clay is a mixture of several aluminosilicates. The main chemical components are two oxides of Al2O3 and SiO2, and the impurities are mainly oxides of alkali, alkaline earth, iron, titanium,

Bauxite in the refractory industry usually refers to the bauxite with calcined Alumina more than 48% and low Ferrum content.. Refractory materials refer to inorganic non-metallic materials with
