Calcium aluminate powder

The main mineral composition for the CaO Al2O3. Calcium aluminate has a strong activity, is one-step production of acid-soluble.
Product Description
Calcium Aluminates powder, its main mineralogical composition is CaO.AL2O3 and CO2.AL2O3 which have stronger
activity, is an idea raw material for producing water treatment chemicals such as Hydroxyl Aluminium Chloride and Poly
Aluminium Chloride, etc. In addition to the excellent acid,solubility, it has the properties of high efficiency,low cost, good
performance, fast reaction and good filtration. Using Calcium Aluminate powder to produce water treatment agent by one
step acidsoluble process is a unique invention in China. This technique can reduce much labor power and save
electric power, then greatly low the production cost.
Application
Mainly used for the material of producing aluminum sulfate, polyaluminum chloride, crystal aluminium, and the substitute of aluminium hydroxide powder. Showing features of lowprice and high aluminium content.
Storage
In a dry place against moisture. Avoiding poisonous substance contaminated and to be exposed to heat and moisture
during storage and transportation. Package must not be damaged.
