Calcined Alumina Description:
Wilead Company provide
1: Calcined Alumina for fine structural ceramics
2: Calcined Alumina for electric ceramics
3: Calcined Alumina for refractory
4: Calcined Alumina micro powder for stainless steel polishing
The calcined alumina of our company is produced by the general international law of Bayer,boron free rotary kiln calcined, in addition to sodium washed by water, greatly improving the product quality,purity and stability, and the bulk density of ceramic products, mohs hardness and ability to withstand voltage,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.
The advantages are 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 sinter ability.
