Alumina

High Temperature Alumina

The appearance of the product is white fine sand or powder, uniform particle size, easy to disperse, and has good sintering performance. This product is the basic raw material for the production of heat-resistant and corrosion-resistant products, such as high-aluminum refractories, ceramic products, spark plugs for automobiles, electronic Ceramic parts, steel charge, high temperature friction materials and raw materials in polished abrasive products.

Industrial Grade Alumina

Industrial grade alumina is a kind of transition phase alumina, which has strong activity, can be dissolved in acid or alkali solution, and has strong water absorption properties in air. It has hydraulic properties and can hydrate with water to form aluminum hydroxide gel with high strength. Since this product is pure alumina phase, with few impurities, high purity, and no low co-soluble phase, it can be used as a molding binder for high temperature refractory materials (low cement or no cement) castables to improve the refractory and slag corrosion resistance of refractory products.

High Temperature Low Sodium Alumina

1. The specification of alumina polishing powder is white crystalline powder, composed of alumina, which is controlled by special processing to obtain good particle size distribution and hardness to meet the needs of various polishing applications.

γ alumina

Gamma alumina is made by dehydration of aluminum hydroxide at a low temperature of 140-150 ° C. It is also called activated alumina and aluminum glue in industry. Oxygen ions in its structure are approximately tightly packed in the center of the cubic face, and AL3 + is irregularly distributed in the octahedral and tetrahedral voids surrounded by oxygen ions. Gamma-type alumina is insoluble in water and can be dissolved in strong acid or alkali solutions.

Medicinal Adsorbed Alumina

Medicinal adsorbed alumina is an alumina with a special structure processed and produced by a special process. It is non-toxic, tasteless, odorless, and white fine sand. It has high chemical purity, strong adsorption performance, fast solution transmission rate, and good decolorization effect., easy to regenerate, long service life and other characteristics, strong water absorption in the air, invariant after water absorption, can be restored by drying at 110 ° C., insoluble in water and organic solvents, soluble in strong acid and alkali solution at high temperature.

Active Gamma Alumina

Main uses: used in the production of chemical catalyst support, alumina active adsorbent, chromatography agent, desiccant, etc.

Plate Corundum

Sintered plate corundum The product is white granular or powdery, and is sintered at high temperature by alumina grinding. Its notable features are: good thermal shock stability; high purity, complete crystallization, and the products produced with this product are resistant to erosion, initialize, corrosion, and long service life.

Ultra High Temperature Calcined Alumina

High temperature calcined alumina is a white powder calcined at 1700 ° C -1800 ° C and then ground. It has high hardness and good thermal conductivity. It can be used as a polishing material or a thermally conductive material in electronic potting materials.

High Purity Ultrafine Alumina

High-purity alumina powder is a white powder with uniform particle size, low water storage and stable chemical properties. This product is used as a raw material for high-aluminum refractories, ceramic devices, automotive spark plugs and polishing and grinding products. It is the basic material for the production of high-aluminum amorphous refractories and a high-quality filler to enhance the performance of refractory products.
