Performance:The gamma alumina is an odorless, tasteless white powder. It is an unstable crystal form, which transforms into θ-phase alumina at 1000 ℃ and α-alumina with stable crystal form at 1180 ℃. The primary particle size is 6-10nm, and the nanoparticles are transparent or translucent. BET is 100~400m2/g, the specific surface area is large, there is a great surface chemical activity.
Use:Fillers, catalyst carriers, desiccants, adsorbents, cleaning agents, coating on the inner wall of the lamp tube, artificial gemstones, inorganic membranes, etc.
Packing:Composite carton packaging, lined with plastic film bag, net weight 10 Kg/bag.
Storage:Sealed and stored in a cool, dry, well-ventilated place, away from direct sunlight.
