Participants

Reactant 2

HCID 1118Sulfuric Acid

HCID 10176082Aluminum Hydroxide

Product 1

HCID 24850Aluminum Sulfate

Procedure

According to a further method, the aluminum hydroxide obtained above as an intermediate product or a highly aluminous clay mineral is reacted with sulfuric acid to obtain aluminum sulfate. Then, aluminum hydroxide is precipitated by neutralization with alkali, followed by filtration and water-washing. Thereafter, the resulting slurry is subjected to wet pulverization using a beads mill or a pot mill and subsequent spray drying into a spherical alumina.
