Electronic grade aluminium sulfate

Product Specification

ELECTRONIC GRADE ALUMINIUM SULFATE 

Product name: Electronic grade aluminium sulfate 

Molecular Formula: Al,(SO,),-18H,O 

Molecular Weight: 666.43 

Property: White and lustrous crystal.granular or powder. Heated at 85'C, it will lost some crystal water and become white powder. At 600'C, it is decomposed into aluminium trioxide. It is soluble in water, nearly insoluble in alcohol. Its water solution is acidic. Electronic Grade Aluminium Sulfate is obtained by purifying on the basis of ordinary aluminium sulfate, which minimizes the content of metal ions such as calcium,magnesium,sodium,iron and so on 

APPLICATION 

It is widely used in cathode materials of lithium ion batteries and electronic chemical industry. 

PACKING 

Non-woven bag with lining, 25kg/bag.
