Detailed Product Description

White crystalline powder high purity activated alumina industrial adsorbents insulating coating

Product name: high temperature calcination N series

 

Overview:

Using rotary kiln, high temperature calcined alumina can be calcined to form α Crystalline phase at temperature of 1380 ℃ -1430 ℃. Alumina crystalline phase has the advantages of high stability, high transformation rate, and low impurity content. The products made from it have the characteristics of high mechanical strength, stable shrinkage, wear resistance, corrosion resistance, and high temperature resistance etc..

Application area: various abrasive materials and tools, abrasion-resistant packing,refractory materials, electronic equipment, mechanical components, sanitary ware, resin filler etc..
