Product Description:

Under 325 Mesh Calcined Alumina Powder AL2O3


Introduction:

The main material of our refractory castable high alumina powder  is Al2O3—SiC—C, there’s 2 types including baking casting material and free baking material, the width of iron runner is required above 2.4 meter, the depth is above 1.7 meter,it has a good performance in site operation, with easy repair, tapping iron is allowed after pouring finished. Although the invest is more higher for once time, but it will be with a longer service life and a few mending work. Refractory castable is the production and the most widely used a monolithic refractories.

 

Application:

It can be used to formulate unshape refractory material; expansive cement, self-stressing cement, addition material of chemical construction material and projects with special requirements.

 

aluminum oxide property:

It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives , polishing, precision casting and so on .

white fused alumina grits&powder chemical composition

 

aluminum oxide property:

Soluble in water white solid. Odourless. Tasteless. Qualitative very hard. Easy absorption of moisture and not ChaoXie. Both sexes oxide, soluble in inorganic acid and alkaline solution, almost insoluble in water and the polar organic solvents. The relative density (d204) 4.0. Melting point about 2000 °C.
