Wasserfreies Kaliumcarbonat (Pottasche)

Potassium carbonate is a white crystalline substance, highly soluble in water, strongly hygroscopic, occurring in the form of a white powder. Potassium carbonate in horticulture can be used together with preventive measures to protect against fungi and other threats. Potassium carbonate is helpful in combating, for example, apple scab, powdery mildew, or mold - common diseases of fruit trees that fruit growers struggle with. It stops the development of powdery mildew, scab, and gray mold, thanks to which plants are free from structural defects. A single dose is approx. 7 kg/ha. It can be used multiple times during the season. The advantage of using potassium carbonate in horticulture is effective prevention of trees against fungi, certainty of the agent's action at a relatively low cost. As a fertilizer used for acidic soils, it is used to fertilize the soil with potassium. Potassium carbonate is used in the production of household chemicals and cosmetics. It is used in the production of detergents, soft soaps and shampoos. In the ceramic industry, used as an additive in production. In the glass industry, it is involved in the production of optical and lighting glass. Used in the photographic industry; to obtain other potassium compounds. Also for the production of paints and pigments. Used in the textile and leather industry, in the drilling industry, and as a mild de-icing agent.
