Mainly used in the storage of solar energy, making use of the heat storage function of melted potassium nitrate and sodium nitrate at high temperature.

Packing:
In woven bags lined with PE bags, 5kg-1500 kg per bag. The package bag can be customized.

Protection Measures:
The production personnel should wear not only breathing mask to prevent the inhalation of potassium nitrate dust and to protect breathing organs, but working clothes and latex gloves to protect the skin.

Storage and Transportation:
Potassium nitrate should be stored in a cool, dry, well-ventilated warehouse; kept away from moisture, rain, sunshine, fire and heat. Temperature in warehouse should not exceed 30. Relative humidity should be less than 80%. It should be kept away from reducing agents, acids, combustible (flammable) material, and active metal powder to avoid mixing storage. Storage areas should be equipped with appropriate material to collect leakage.
