Inorganic substances refer to substances composed only of inorganic substances or mixed with other substances. It usually refers to materials obtained through a certain process from raw materials such as silicate, aluminum, borate, phosphate, germanate, or oxide, nitride, carbide, boride, sulfide, silicide, and halide. . Inorganic materials can generally be divided into two categories: traditional materials and new inorganic materials. Traditional inorganic materials refer to materials with silicon dioxide and its silicate compounds as the main components, so they are also called silicate materials. The new inorganic materials are made of oxides, nitrides, carbides, sulfides, silicides and various non-metal compounds, using special advanced technology. Inorganic materials have different characteristics, depending on the usage. Generally speaking, inorganic materials have high heat resistance, corrosion resistance, durability and high strength. Some materials have good conductivity, some materials have good conductivity, and some materials have self-cleaning function. Due to the wide variety of inorganic materials and different properties, their uses are also quite wide, and they have received sufficient attention, especially in recent years, new materials It has caused widespread concern.
