Inorganic chemical industry is the abbreviation of inorganic chemical industry. It uses natural resources and industrial by-products as raw materials to produce inorganic acids such as sulfuric acid, nitric acid, hydrochloric acid, and phosphoric acid, soda ash, caustic soda, synthetic ammonia, chemical fertilizers, and inorganic salt. The main raw materials of inorganic chemical products are sulfur, sodium, phosphorus, potassium, calcium and other chemical minerals and coal, oil, natural gas, air, water and so on. In addition, by-products and wastes in many industrial sectors are also raw materials for inorganic chemicals, such as: coke oven gas in the coking production process in the iron and steel industry. The ammonia contained in it can be recovered by sulfuric acid to make ammonium sulfate. Sulfur dioxide in the smelting exhaust gas of lead ore and sphalerite can be used to produce sulfuric acid. The inorganic chemical industry includes sulfuric acid industry, soda ash industry, chlor-alkali industry, synthetic ammonia industry, chemical fertilizer industry and inorganic salt industry. In a broad sense, it also includes the production of inorganic non-metallic materials and fine inorganic chemicals such as ceramics and inorganic pigments.
Inorganic chemical industry is a basic raw material-material industrial product with wide application and large demand. Its uses involve the paper industry, rubber, plastics, pesticides, feed additives, trace element fertilizers, space technology, mining, oil extraction, navigation, high-tech fields in the information industry, electronics industry, and various material industries, as well as people in daily life Clothing, food, housing, transportation, light industry, environmental protection, and transportation are closely related.
