Fluxing agent -- Aluminum Phosphate

Color:White powder The PH value:2-4 Residue on sieve( 45um):max0.5% P2O5 %:60-70 Al2O3 %:30-40

Condensed Aluminum Phosphate

 

1.Properties :

Condensed aluminum phosphate is a type of colorless and odorless white crystalline powder, insoluble in water but freely soluble in chlorhydric acid or nitric acid.

It will turn into colloid instead of melting at high temperature. In polyreaction, it will form

stable a-ALPO4.

 

2.Applications:

 It is mostly used as binder and curing agent in the production of hi-temp refractory materials for kiln. It also serves as fluxing agent in the production of special glass, as binder in fabrication of ceramics or tooth, and as catalyst in organic synthesis.
