Product Description

1.Calcined alumina introduction
     
        High tempreature calcined alumina powder is produced from industrial alumina used as raw material, at
the appropriate temperature calcined into crystalline stable alpha alumina as raw material after
the ball into alumina powder. Can be widely used in such as electronic equipment, structural    
ceramics, refractory material, wear, polishing materials,etc.
 
2.Calcined alumina feature
 
  (1) High melting point abd excellent mechanical strengh
 
  (2) High strengh and stiffness
 
  (3) Featured with small tempreature difference and long socking time
 
  (4) High crystal phase transition rate and good batch stability
 
  (5) It is easy to mill, and the milling time can be reduced by 10%-15%
 
  (6) Excellent dielectric properties (from DC to GHZ frequencies)
