Monoaluminum Phosphate Binder
Synonyms: Mono-aluminum (aluminium) phosphate; Aluminum (aluminium) phosphate monobasic; Aluminum (aluminium) dihydrogen phosphate; Aluminum tri(dihdrogen phosphate)
CAS No.: 13530-50-2 EC No.: 236-875-2
Molecular Weight: 317.94
Solubility: miscible in water.
Industrially, monoaluminum phosphate binder may be manufactured by acid-base neutralization process between high purity aluminun hydroxide Al(OH)3 and phosphoric acid 85%. By controlling reactant's pH value, reaction can be managed at level that just one free proton is neutralized. The final products have two types: viscous liquid (aqueous solution) and solid powder. Reaction equation is given as follows:
Monoaluminum phosphate is industrally applied as high-temperature binder for ceramic, silicon steel & refractory material etc. Our product is specially designed for these purposes, widely accepted by major steel firms such as WISCO, TISCO and Panzhihua Iron & Steeland and many refractory manufactures.
