Activated Alumina powder
1. Product characteristics
This product is produced by rapid calcination with suspension calcinations, the main crystal phase is ρ phase alumina with less impurities, high purity and no co-soluble phase. The product’s important feature is rehydration, from which many different varieties of activated alumina products can be prepared, such as rods, spheres etc.
2. Product applications
The product is used as raw material of activated alumina ball, and can be used as a binder for high-grade amorphous refractory castable instead of pure calcium aluminate cement, improving the refractoriness and slag resistance of refractory products. It can also replace silicon micropowder and alumina powder as a binder for high-grade corundum products, high-grade ceramics, catalyst carrier, medicinal adsorbent and specific catalyst raw materials. As a high-end adhesive, it has been widely recognized, especially with The refractory industry continues to undergo transformation and upgrading, and the market prospects are promising.
3. Product specifications
The product implement the standard of Q/CHALCO A016-2012.
