superfine white activated alumina

1.Excellent thermal stability
2.Activated alumina is used in drinking water,to remove F, As, color and smell. Easily operated.

Activated alumina;
Chinese name. [English] active Alumina Alumina controller name, Reactive alumina, Um alumin controller (I) oxide catalyst in the noun "used in explanation of alumina usually only called" the activated alumina ", it is a kind of porous, high dispersion of solid material, a large surface area, its pore surface has required the catalytic properties, such as adsorption, surface activity, high thermal stability, etc, so widely used for chemical reaction and catalyst carriers.

[
editor this segment] purposes
High-performance activated alumina in monolithic refractories ingredients can bring benefits below: improving the body density, liquidity and strength, improve the second mullite relic, reduce the quantity and porosity. In addition, still can make the activated alumina desiccant, water quantity, the drying speed is fast, can regenerate (400-500K roasted). The activated alumina belongs to the category of alumina, mainly used in chemical, catalyst and DTC absorbent, catalytic carrier, according to different purposes, the raw material and preparation.
