Bauxite is often used as raw material for high-alumina refractories and fused brown corundum. Bauxite used in refractories industry usually refers to bauxite with calcined Al2O3>=48% and low Fe2O3 content. The calcined bauxite has a fire resistance of 1780 ℃, strong chemical stability and good physi

Fire resistance is the property of the refractory material bauxite that can resist high temperatures during use without melting. Fire resistance is one of the important indicators for evaluating the quality of refractory materials. If the fire resistance is not high, during use, due to prolonged exp

Calcined bauxite is mainly used to produce high-alumina refractories. It is one of the most important raw materials for shaped and unshaped refractories produced in steel, casting, glass and cement industries. It can also be used to make fused brown corundum.

Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants.

SEPPE calcined bauxites are aggregates formed from aluminium ore which has been subjected to calcination, a heat treatment process. When calcined, SEPPE bauxite has exceptional physical hardness and stability, leading to excellent resistance to abrasion caused by the vehicle's tyres and a high resis

Refractory materials are the basic materials for high-temperature industrial kilns and facilities. Mainly used in the fields of refractory insulation and kiln lining and facility insulation in industries such as metallurgy, petrochemicals, non-ferrous metals, building materials, mechanical manufactu

High alumina bauxite aggregate is of high quality refractories by alumina raw materials through selection, roasting, crushing, processing of the project etc.. Bauxite aggregate with high aluminum, low iron and high hardness, low coefficient of thermal expansion, high refractoriness, thermal stable p

The four major properties of high fire resistance, lightweight insulation and high strength, fine-grained large surface area are integrated, doubling the value of cenospheres. No other lightweight insulation material can match this. It is not excessive to say that it is the king of insulation materi

SEPPE high alumina bauxite has a refractoriness of up to 1780°C, strong chemical stability and good physical properties.Calcined bauxite is categorized according to various industries such as refractory, cement, metallurgical and chemical. These are used as raw materials in refractory bricks which a

Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants.The main chemical composition of cenosphere is silicon and aluminum oxide, of which silicon dioxide is about 50-65% and aluminum oxide is about
