What are the differences between industrial potassium carbonate and agricultural potassium carbonate?

potassium carbonate

Agricultural potassium carbonate is different from potassium sulfate, potassium nitrate, potassium chloride, potassium dihydrogen phosphate and potassium fertilizer. It is extracted from plants, the physicochemical properties of hot and quick, physiological alkaline fertilizers also contain plant bionic, resistance factor, prevention and treatment of soil sterilization and good underground pest. In addition, it can increase soil temperature, neutralize soil acidity, and cause crops to grow in suitable soil pH environments. The carbonate for photosynthesis of plant material, and loose soil. Supplement of potassium nutrition supplement for crop seeds, return the harvest from the soil trace elements from various shift (calcium, magnesium and silicon, boron, iron, zinc, copper, manganese, molybdenum, selenium etc.). All kinds of mineral elements contained in plants contain almost all of them, and their nutrients are water-soluble and readily available. They are rare varieties of potash fertilizer used in agricultural production. Due to the limitation of raw material sources, China can not be industrialized and produced in large quantities. The content of agricultural potassium carbonate (K2CO3) in Indonesia can be as high as 50%.

Industrial potassium carbonate is colorless or white, six square or orthorhombic crystalline or granular powder. The relative density is 2.662, the conversion point is 588, the melting point is 1069, and the boiling point is 1689 centigrade. Soluble in water (12G / 100ML at 25 DEG C, 24.1G / 100ML at 100 DEG C), insoluble in alcohol, acetone, and carbon disulfide. Bitter salt. It is the raw material for producing electron tube, TV set, picture tube and computer monitor glass bulb. It can be used to produce optical glass to improve transparency, intensity and refractive index. Also used in the production of welding electrodes, welding can prevent arcing phenomenon. Is a food additive potassium sorbate, potassium dihydrogen phosphate as raw material. Can be used as foliar fertilizer, also can be used as raw material of compound fertilizer. It can be used in the production of dyes and dye the white ice. An absorbent used to remove hydrogen sulfide and carbon dioxide. Mixed with soda ash can be used as dry powder extinguishing agent. It can also be used as auxiliary raw material for acetone and alcohol production and anti-aging agent in rubber production. Aqueous solution can be used in the cooking of cotton and wool degreasing. It is also used in printing ink, photographic medicine, polyester, explosive, electroplating, leather making, ceramics, building materials, crystal and medicine production. Used in the production of instant noodles, carbonated drinks additives, played a role in swelling and corrosion.

Agricultural potassium carbonate is extracted from plants, and it is a kind of loose, hot and quick acting fertilizer. More than 50%, 35% containing potassium carbonate potassium carbonate, 18.8%. Also contains phosphorus, calcium, iron, magnesium, silicon, boron, zinc, iron and other effective trace elements in water soluble nutrients. The potassium can promote the synthesis and transport of nitrogen and carbohydrate metabolism in plants, can promote the healthy plant growth, enhance the ability of resistance to insects and natural disasters, in addition also has to improve drought resistance of crop photosynthesis; carbonate is nutrients, can promote and improve the photosynthesis of plants. Agricultural potassium carbonate is widely used in fruit and vegetable production.
