Storage and Transportation:

1. Store in a ventilated and dry warehouse. Potassium Carbonate should not be stored in a cargo shed or in the open, and should be protected from moisture. When transporting, loading and unloading, it should be protected from rain to ensure that it is dry and the packaging is not damaged and polluted.

2. Potassium Carbonate cannot be stored and transported together with acids. Water can be used for rescue in case of fire. 3. Potassium Carbonate cannot be mixed with organic matter and sulfur for transportation.

Packing: Outer woven bag or paper-plastic composite bag, lined with plastic bag, paper-plastic composite bag, net weight of each bag is 25kg, 50kg, 1000kg.


1. Potassium Carbonate is mainly used for foliar spraying fertilizers, and can also be used as a raw material for compound fertilizers, TV glass bulbs, welding rods, food additives, pharmaceuticals, hydrogen peroxide, film films, ceramics, printing and dyeing, potassium glass and other industries. It is also important of inorganic chemical raw materials.

2. Potassium Carbonate is used as an auxiliary raw material for the production of acetone and alcohol and an anti-aging agent in the production of rubber.

3. Potassium Carbonate can be used in the production of inks, photographic drugs, polyesters, explosives, electroplating, tanning, ceramics, building materials, and crystals.

4. Potassium Carbonate is also used as an additive in the production of instant noodles and carbonated beverages, and plays a role of leavening and antiseptic.
