Aluminum Sulfate Powder Low Price 16% 17% Non Iron for Drinking Water Treatment1
4 year ago
Solubility: soluble in water, insoluble in ethanol and so on.
Industrial product is grey-white flakes, granules or lumps, with light greenish colour due to low iron salts, and yellowish surface due to oxidation of low iron salts. The crude product is grey-white fine crystal structure porous.
Chemical structure formula of Aluminium Sulphate
Extremely soluble in water, Aluminium sulphate can not be dissolved in pure sulphuric acid (just coexist), in sulphuric acid solution and sulphuric acid together dissolved in water, so aluminium sulphate solubility in sulphuric acid is Aluminium sulphate solubility in water.
It decomposes at 770°C into aluminium oxide and sulphur trioxide.
There are anhydrous and octadecahydrate. Anhydrous material is colourless rhombohedral crystal system. Soluble in water, aqueous solution is acidic, slightly soluble in ethanol. The solubility in water increases with the rise of temperature. Octadecahydrate (Al2-(SO4)3-18H2O) is a colourless monoclinic crystal. Soluble in water, insoluble in ethanol. The aqueous solution is acidic due to hydrolysis.
Relative density (water=1): 2.71

（1）Catalysts and Auxiliaries：The catalyst is the active component that really acts as a catalyst and reduces the activation energy of the reaction. The additives, on the other hand, are auxiliary components, either structural additives or electronic additives, which can improve the stability of the catalyst, while the electronic additives can modulate the electronic properties of the catalyst.Our main Catalysts and Additives products include Plastic additives、Water treatment agent.
（2）Our Petrochemicals include special oils and fats, petroleum product additives, petroleum waxes and so on.
