Description
Aluminium Hydroxide powder, used in epoxy resin, rubber, plastic and other products as flame retardant filler, it can improve the fire resistance, arc resistance, also increase product strength.
Chalco also manufactures the high purity aluminum hydroxide with 4N or higher content. The appearance is white crystalline powder, and typical characters includes uniform grain size, high purity, stable chemical properties, good crystal phase stability, and good sintering activity. It is an excellent raw material for preparing high-pure alumina and transparent ceramics, petroleum, chemical catalysts, gems and other industries. We also have high purity alumina with 4N.
4N High Purity Alumina
It has white crystalline powder or fine sand appearance, uniform particle size, low water consumption, stable chemical performance, good crystalline phase stability, insoluble in acid and alkali, and good sintering activity. It is used in the fields of sapphire crystal raw materials, tricolor phosphors, long afterglow phosphors, high pressure sodium lamp tubes, glass additives, electronic ceramics, catalyst carriers and so on.
