Physical and chemical indicators of high quality 85% calcined bauxite

2022-05-25

The bauxite referred to in the refractory industry usually refers to the bauxite with Al2O3>=48% after calcination and low Fe2O3 content. The clinker is gray-white, light-yellow, and dark-gray. It is mainly used for high-alumina refractories, and can also be used to make fused brown corundum. High alumina bauxite clinker is classified according to the content of AL2O3 and impurities such as Fe2O3, TiO2, CaO+MgO, K2O+Na2O, and clinker bulk density and water absorption.

Physical and chemical indicators of bauxite

The use of bauxite

(1) Board or woven into cloth to replace refractory bricks lining high-temperature furnaces in smelting, chemical, glass, and other industries. Firefighters can use a fire-resistant fiber cloth to make clothes.

(2)  85% calcined bauxite using magnesia and bauxite clinker as raw materials, adding an appropriate binder, is very effective for pouring the overall lining of the ladle.

(3) Manufacture of various compounds of alumina cement, abrasive materials, ceramic industry, and chemical industry that can make aluminum.
