Sodium aluminium sulfate is the inorganic compound with the chemical formula NaAl(SO 4) 2 ·12H 2 O (sometimes written Na 2 SO 4 ·Al 2 (SO 4) 3 ·24H 2 O). Also known as soda alum , sodium alum , or SAS , this white solid is used in the manufacture of baking powder and as a food additive .
Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate ( anhydrous ) is a white crystalline solid having a formula variously given as NaAlO 2 , NaAl(OH) 4 ( hydrated ), [ 3 ] Na 2 O·Al 2 O 3 , or Na 2 Al 2 O 4 .
Sodium aluminosilicate refers to compounds which contain sodium, aluminium, silicon and oxygen, and which may also contain water. These include synthetic amorphous sodium aluminosilicate, a few naturally occurring minerals and synthetic zeolites. Synthetic amorphous sodium aluminosilicate is widely used as a food additive, E 554.
Aluminium sulfate is sometimes called alum or papermaker's alum in certain industries. However, the name " alum " is more commonly and properly used for any double sulfate salt with the generic formula X Al(SO 4 ) 2 ·12H 2 O , where X is a monovalent cation such as potassium or ammonium .
Potassium alum may be an acidic ingredient of baking powder to provide a second leavening phase at high temperatures (although sodium alum is more commonly used for that purpose). [citation needed] For example, potassium alum is frequently used in leavening of youtiao, a traditional Chinese fried bread, throughout China. [45]
