Phosphate compounds are used in refractories
For strict service applications, include
Gasification, glass melting, metal processing;
Influence the strength and corrosion of refractory materials
Resistance. Phosphates and other things
Used for a refractory material, particle size determination and
Porous finished refractories. How about a refractories

The environment (oxygen partial pressure and
Temperature) affects phosphate phase formation or
Existing during industrial service. The data will be

C stands for Aluminum metaphosphate
And 1220 oC is aluminum orthophosphate, with
The gaseous byproducts of the reaction are O2 and PI
