Aluminum industry is currently being developed and adopted sandy alumina, such as alumina having a high activity, readily soluble in cryolite solution, and better able to absorb hydrogen fluoride electrolyzer flue gas, flue gas cleaning in favor . The chemical composition of aluminum with alumina generally as follows: Al2O3> 98.35% Fe2O3 0.01 ~ 0.04% SiO2 0.01 ~ 0.04% TiO2 <0.005% ZnO 0.003 ~ 0.02% CaO 0.007 ~ 0.07% Na2O 0.3 ~ 0.65% V2O5 <0.003% P2O5 < 0.003% Cr2O3 <0.002% Loss on ignition 0.2 to 1.5% alumina, activated alumina is usually used specifically referred to as "activated alumina" in the catalyst, which is a porous, high dispersion of solid materials activated alumina, there offer a large surface area activated alumina, with its porous surface catalysis of the required characteristics, such as adsorption, surface activity, good thermal stability, so widely used as catalysts and catalyst supports chemical reactions. Use high-performance activated alumina in monolithic refractories ingredients can bring the following benefits: Increased body density, mobility, strength, improve secondary mullite Dan Shengcheng amount, reduce the amount of water and porosity. Also flourishing production of activated alumina, activated alumina can be done desiccant, water volume, fast drying GB activated alumina, can be reproduced (400 -500K baking). Activated alumina is the scope of alumina chemicals, mainly used adsorbents, purifying agent, catalyst and catalyst support, depending on the use of its raw materials and preparation methods.
