Inorganic compounds usually refer to compounds that do not contain carbon but include carbon oxides, bicarbonates, carbonates, cyanides, etc. Inorganic compounds have a variety of conventional uses, and the following are some of the main application areas:

1. Building materials
Inorganic compounds play an important role in the construction industry. For example, calcium sulfate can be used to make building materials such as cement and gypsum, which are widely used in the construction field.

2. Industrial production
Inorganic compounds play an irreplaceable role in industrial production. Some inorganic salts are commonly used additives in steel and non-ferrous metal smelting, which help to improve production efficiency and product quality. In addition, inorganic acids such as sulfuric acid and nitric acid are important raw materials for the industrial production of various inorganic substances.

3. Agricultural field
Inorganic compounds are also widely used in the agricultural field. Inorganic fertilizers can improve soil fertility and crop yields, and inorganic pesticides can prevent and control crop diseases and pests, and improve crop disease resistance and insect resistance. At the same time, inorganic plant growth regulators can regulate plant growth and development, further improving the quality and yield of crops.

4. Daily life
Inorganic compounds can be found everywhere in daily life. For example, table salt (sodium chloride) is an indispensable condiment in people's daily lives, and it can also be used to prepare chlorine. Baking soda (sodium bicarbonate) is often used in baking, cleaning, and other fields.

5. Medical field
Inorganic compounds also have a wide range of applications in the medical field. For example, physiological saline (sodium chloride solution) is often used for infusion and cleaning wounds in medicine. Drugs such as aspirin also contain inorganic compounds, which have antipyretic and analgesic effects.

6. Environmental protection field
Inorganic compounds also play an important role in the field of environmental protection. For example, some inorganic compounds can be used to treat industrial wastewater and reduce the concentration of harmful substances in wastewater. At the same time, inorganic compounds can also be used in air purification, soil remediation, and other fields, which helps to improve environmental quality.

7. New energy field
Inorganic compounds also have broad application prospects in the field of new energy. For example, inorganic compounds can be used in the manufacture of solar cells to improve the efficiency of photoelectric conversion. In addition, inorganic compounds can also be used as catalysts for fuel cells to reduce the activation energy of the reaction and improve battery performance.

In summary, inorganic compounds have many common uses and are widely used in the fields of construction, industry, agriculture, daily life, medical treatment, environmental protection, and new energy. These applications not only improve people's quality of life but also promote social progress and development.
