Product:Potassium Carbonate Industrial Grade
Molecular formula: K2CO3
Molecular weight: 138.19
CAS-No. : 584-08-7
EC-No. : 209-529-3
Properties
Potassium Carbonate Industrial Grade is Monoclinic crystals, white powder, granular crystals or prills. Easily soluble in water forming a slightly alkaline solution. Insoluble in alcohol and ether. It is strongly hygroscopic and it easily cakes and turns into Potassium bicarbonate through absorbing carbon dioxide when exposed to the air for a long time.
It is chemically stable under standard ambient conditions (room temperature)
Usage of Potassium Carbonate Industrial Grade:
- It can be used as raw materials in manufacturing electro tube, TV kinescopes and computer displays.
- 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 can be use as desiccant in chemical experiments.
- It can be used as fertilizer in agricuture.
