According to the different alumina content, our fused alumina can be divided into brown fused alumina, white fused alumina, pink fused alumina, black fused alumina, zirconia fused alumina etc.

Different Types of Fused Alumina

Brown Fused Alumina

High bulk density, low iron, good crystallization, strong fluidity, low coefficient of linear expansion, corrosion resistance.

White Fused Alumina

High purity, high hardness, low sodium.

Zirconia Fused Alumina

Tenacious texture, dense sturcture, high strength.

Pink Fused Alumina

High toughness, acid and alkali corrosion resistance, high temperature resistance, good thermal stability.

Black Fused Alumina

Moderate hardness, high toughness, high temperature resistance, stable thermal performance.

Advantages of Haoyun Fused Alumina

We have two special designed production lines to make the different shapes of grains for the variety of applications.

Fused Alumina Manufacturing Process

The high quality bauxite is obtained in Shanxi Province and Henan Province as the main raw material to smelt brown fused alumina. The details are as follows:

Requirements for alumina content: Al2O3: 87-88%, the alumina content should not be less than 85%.

Silica content requirements: SiO2 content of bauxite should not exceed 4%, which is basically maintained between 2-3.4%.

Bulk density of high alumina material: bulk density at least 2.3-2.5g/cm3.

Others: CaO+MgO should not be higher than 0.6% or 0.8%, generally the lower the better. Regarding the problem of high CaO content in brown fused alumina, CaO content of the bauxite is required to be as low as possible, or the refining time of brown fused alumina is adjusted to achieve the purpose of reducing impurities.

As a professional fused alumina manufacturer, we provide fused alumina manufacturing process, al2o3 fused, ceramic abrasive grain, monocrystalline fused alumina, ceramic abrasive media, etc. Want to know what is fused alumina or fused alumina uses, contact us.
