Calcined alumina

1) Excellent performance,a-AL2O3 95min 2) Competitive EXW price 680$ 3) Ideal refractory raw materials 4) 10,000 tons/year

Description:

We mainly provide following alumian products: a-AL2O3 for fine structural ceramics, a-AL2O3

for electric ceramics, a-AL2O3 for refractories, a-AL2O3 micro powder for stainless steel

polishing.

Product Feature:

(1) The first set of tunnel kiln with the length of 120m in China for producing a-AL2O3.

(2) Featured with small temperature difference and long socking time.

(3) High crystal phase transition rate and good batch stability.

(4) The produces with different grian sizes can be produced with composite additive upon        the customers' request. 

(5) It is easy to mill, and the milling time can be reduced by 10%-15%.

(6) The slurry has good flowaility for hot pressing.
