Storage conditions
1. It should be stored in a cool, ventilated, dry, and clean warehouse, protected from moisture, high temperature, and pollution from toxic and hazardous substances. It should not be stored and transported together with toxic and hazardous substances.

2. Protect from rain and scorching sun during transportation. Be careful when loading and unloading, so as not to break the package.

3. In case of fire, water, sand and various fire extinguishers can be used to put out the fire.

Stability
1. Approximately 8% of ammonia can be lost in the exposed air. 1g of this product is soluble in about 2.5mL of water, slightly soluble in ethanol, but insoluble in acetone.

2. The aqueous solution is acidic, and the pH value of 0.2mol/L aqueous solution is 4.2. It is relatively stable in the air, and a small part of it decomposes at 100°C. When heated to above 130°C, it gradually decomposes and loses ammonia and water, forming a mixture of ammonium metaphosphate and phosphoric acid.

3. Easily soluble in water, slightly soluble in alcohol, insoluble in acetone. It is relatively stable in the air, and a small part of it decomposes when heated to 100°C. Above the melting point, ammonia and water are lost, and a mixture of ammonium metaphosphate and phosphoric acid is formed. The aqueous solution is acidic (the pH value of a 1% solution is 4.5). Decomposes at 190.5°C. It has piezoelectric properties. It changes from a tetragonal crystal system to an orthorhombic crystal system at low temperatures (-125°C), which is similar to potassium dihydrogen phosphate.
