Advantages of a Phosphate-Binder System for Refractory
Apr 07 2005 · Heat-setting phosphate-bonded castables are based on the Al2O3-SiO2-P2O5 system. Cold-setting phosphate-bonded castables are based on the Al2O3-SiO2-P2O5-MxO system (MxO = alkali or alkali earth oxide). The most used phosphate binder in the refractory industry is monoaluminumphosphate (MAP) in liquid or spray-dried form.
