What is the properties of Potassium carbonate?

Potassium carbonate is white power, small granular crystallization, was dissolves in water absolutely, and generates alkaline solution. Potassium Carbonate has improvement of plant photosynthesis and improve soil structure and provide nutrients, widely used in agriculture area. Also 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.

-- Potassium carbonate is soluble in water and insoluble in ethanol.
-- Potassium carbonate is a white salt at room temperature often appears as a wet solid.
-- Potash forms strongly alkaline solution with the water.
-- Vigorous reaction can occur when potassium carbonate is added to water. Dissociation of potassium carbonate in the water solution is an exothermic reaction.
-- The vapour pressure of the potassium carbonate is very low.
-- Potassium carbonate decomposes at a high temperature.
-- Potassium carbonate is a hygroscopic substance and therefore solid potassium carbonate slowly absorbs water from the air.

Preparation of Potassium carbonate

Potassium carbonate is commercially prepared by the electrolysis of Potassium chloride. The resulting Potassium hydroxide is then carbonated using carbon dioxide to form, Potassium carbonate, which is used to produce Potassium compounds. 2KOH + CO2 → K2CO3 + H2O

Where to use Potassium carbonate

Drying Agent

Potassium carbonate is used as a drying agent in the laboratory for ketones, alcohol and amine. Potassium bicarbonate cannot be used as drying agent for highly acidic compound.

Glass Industry

Potassium carbonate is used in the manufacture of specialty glasses, such as optical lenses, television screens and cathode ray tubes. Potash is also used in the pottery industry for glazing pots.

Food Industry

Potassium Carbonate is used as a food additive in the production of grass jelly. It is used to tenderize tripe. German gingerbread recipes often use potassium carbonate as a baking agent. It is also used as a buffering agent in the production of mead or wine.

Fire extinguisher ingredient

Potassium carbonate is an efficient fire extinguishing agent for class B and class C type fire extinguishing agent. It can act as a scavenger of acidic fire ingredient by-products. Potassium carbonate is used as a dry powder fire extinguisher.

Fertilizer Industry

Potassium carbonate is used in the production of fertilizer industry for the manufacture of Potash. About 95% of Potash is used in the fertilizer industry. Potash is utilized in the fertilizer industry due to its advantages such as a taste enhancer to the fruits & vegetables, better restiveness power against diseases, better reservation of power, protection from drought & climatic conditions and to get stronger stems and roots. Potassium carbonate is used as an effective fertilizer for stabilizing pH of the soil and reduces the acidity of soil.

Chemical Industry

It is utilized in the manufacture of soap products. Soap with sodium carbonate is less mild than the commercial usage soaps. Potassium carbonate is used in the preparation of electrolyte for oxyhydrogen production. Potassium carbonate is also used in the water treatment industry for softening of hard water.

Pharmaceutical Industry

Potassium carbonate is used for stability in neurons to maintain equilibrium. In the pharmaceutical industry, Potassium carbonate is used as an antacid, electrolyte replinisher, excipient, leavening agent and pH control agent for medical formulations.

Other usage

Potassium carbonate is used in the polymerization of synthetic fibers and dehydrogenation of olefins. It is used as a detergent builder in detergents and also in cosmetics products. Potassium carbonate can also act as a high temperature polymer blowing agent.
