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

Brown corundum is an artificial abrasive, while garnet is a natural abrasive;Brown corundum is made by bauxite and in a 2200 ℃ electric arc furnace at high temperature. It is brownish red or reddish brown.Garnet abrasives are extracted from rock minerals and processed into various particle sizes th

High Friction Surface Treatment is a cost-effective approach to address areas on roadways, such as horizontal curves, intersections or bridges, that demand higher friction in order to reduce vehicle skidding and save lives. The application process requires broadcasting the aggregate either by hand o
