Product overview

Colorless monoclinic crystals or pearly crystals or white crystalline powders.

The relative density is 1.388.

Odorless and salty.

Easily soluble in water, ethanol and glycerin; Slightly soluble in ammonia and ammonia water; Insoluble in ether.

The water solution is neutral, and the solubility in 100 ℃ water is 667g/lOOg water.

It is easy to deliquescence.

It is stable when it is stored in a dry state.

When it is heated to more than 200 ℃, it will rapidly decompose and release toxic phosphine that can spontaneously ignite.

Applications

In industry, it is the main raw material of halogen-free flame retardant calcium aluminum hypophosphate, because of its high purity, high qualification rate, less impurities and heavy metal compounds in line with the European Union ROHS requirements. Although common bromine chloride flame retardants are effective, they have carcinogenic effects after incineration, so they have been banned in the EU. It is an ideal choice for halogen-free flame retardant production, especially in the industrial plastic flame retardant industry.

In terms of water treatment, the main.
