Calcined Bauxite - Refractory Grade, Al2o3 90% Min, Hardness 9.5, Size: 0-150mm Lumps/powders - Oxidized Surface Treatment, High Refractoriness 1780â°c

We are a reputed name in this industry as a Exporter of Calcined Bauxite in Gongyi, Henan, China. Bauxite, alumina or bauxite, the main ingredient is alumina, the main containing impurities hydrated alumina, a mineral earthy. White or gray, iron and was yellow, or brown dignitaries. hardness 1 ~ 3, opaque, brittle.
Melting extremely difficult. Do not dissolve in water, can be dissolved in sulfuric acid, sodium hydroxide solution.
Used mainly aluminum and steel refractories.

Application:-
1.The bauxite for aluminum industry in defense, aerospace, automotive, electrical, chemical, and daily supplies;
2.Bauxite clinker processed into fine powder and made after the casting mold which is used in military,
aerospace, communications, instrumentation, machinery and medical equipment sector;
3.Bauxite can be used in refractory products. The refractoriness of high-alumina clinker is up to 1780, Its
features are chemical stability strong and physical properties of sound;
4.It can manufact alumina cement, abrasive materials and aluminum compounds.
