Product Details

Product Description

Application:Widely used in
refractory industry, ceramic industry, polishing
industry , etc. Taking the superior industrial
alumina as raw material, Calcined Alumina is produced
through the method of advanced high temperature down
draught kiln with scientific calcine. These make sure
it has the advantages as follows: less trash, high
transfer rate, stable contraction, and great variety of
goods. The shape is fine sand or powdery with white
color, As its equal particle sizes and dispersing
easily, it has a good sinterability. Calcined Alumina
is the basic raw material for heat-resistance and
corrosion-resistance products, such as high-alumina
refractory, high level ceramic products, car used
sparking plug, electronic ceramic parts, material for
iron and steel oven, high temperature friction material
and polishing grinding products, ect.

Advantages: alumina powder, aluminium oxide
powder, aluminum oxide powder

1. 
High hardness and mechanical strength;

2. Excellent thermal and electrical insulation
characteristics;

3. Resists wear, chemically inert, stable at high
temperatures.
