Medium Sodium Calcined Alumina Fine Powder
1. Produat characteristics
The unique raw material pretreatment process is adopted to effectively reduce the harmful impurities of the raw materials before calcination, and the middle sodium calcined alumina series products are produced by high-efficiency and energy-saving rotary kiln, and deep processing is performed, the particle size and particle size distribution range is narrow, the crystal form is stable, shrinkage is stable.
2. Product applications
This product is used as a styling and amorphous refractory material, microcrystalline ceramics, spark plugs and IC electronic substrate ceramics, high alumina ceramics, ceramic roller bars, alumina abrasive materials and glass.Medium Sodium Calcined Alumina Fine Powder
