1. Calcined Bauxite Introduction
Refractory applications remain the premiere non-metal market for calcined bauxite which is mixed with binders and pressed, extruded, cast and shaped into a variety of forms that are then dried and transfered to kilns for firing. The calcined refractory grade bauxite is also used in unfired monolithic refractories.

3. Calcined Bauxite General advantages
4. Calcined Bauxite Characteristics
5. Calcined Bauxite Applications
1.Aluminium and metallurgical industry. Used for national defense, aviation, automobile, electrical appliances, chemical industry, daily necessities, etc.
2.Precision casting. Bauxite clinker processing into fine powder made of mold after casting.Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment departments.
3.Refractory industry: refractoriness of high quality rotary kiln bauxite can reach 1780°C with strong chemical stability and good physical properties.
4.Silicic acid aluminium firefibre. It has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical vibration resistance.Used in iron and steel, non-ferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense and other industries.It is the high aluminum clinker into the melting temperature of about 2000 ~ 2200ºC in the high temperature arc furnace, after high temperature melting, high pressure and high speed air or steam spray, cooling, became white "cotton" -- aluminum silicate refractory fiber.It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical, glass and other industrial high temperature furnace lining firebrick.Firemen can make clothes out of refractory fabric.
5.Mixed with magnesium oxide,it can be an nice bonding agent,especially for pouring entire steel teeming ladle lining.
6.Manufacture bauxite cement,grinding abrasives.ceramic industry,and chemical industry for making aluminium compounds.
7. The manufacture of fired and monolithic refractory products.
8. Chemistry industry for all kinds of aluminium compound.
6. Calcined Bauxite Particle sizes Available
