With the development of refractories industry and social progress, refractories with slow construction speed are gradually replaced, and the amount of unshaped refractories is increasing in the metallurgical industry. The largest amount of sodium hexametaphosphate technical grade used in unshaped refractories is castable, followed by spray coating.

The sodium hexametaphosphate technical grade is mainly used in the refractory castables, refractory plastics and refractory slurries with cement as binder, which usually plays a role of reducing water; according to the needs of preparing different kinds of amorphous refractories, the use of industrial sodium hexametaphosphate in the additives of the amorphous refractories is also different.

Therefore, the sodium hexametaphosphate technical grade produced by Chongqing Chuandong Chemical Group is a new refractory with good performance in phosphate. It has good thermal shock stability, high compressive strength, strong resistance to slag corrosion and impact, high load softening temperature and chemical stability.
