Potassium Carbonate

Potassium Carbonate Applications Potassium Carbonate is used as raw materials in manufacturing electro tube, TV kinescope, computer display. It is applied in optical glass improving clarity, strength and refractive index. It is also applied in electrode avoiding electric arc breaking-off during welding. It is used to produce food additives like potassium sorbate, monopotassium phosphate, etc. Handling and Storage Store in dry and ventilated house away from moisture. Don't store in goods yards or expose to the air. Protect the material from rain when loading and unloading. Be sure to keep the package dry and free from contaminant. Avoid handling and transporting together with acid substances. In the event of a fire, use water as extinguishing agent.
