CAS 7631-86-9: Silica
Description:Silica, chemically known as silicon dioxide (SiO2), is a naturally occurring compound that is abundant in the Earth's crust. It is characterized by its hard, crystalline structure and is commonly found in various forms, including quartz, sand, and glass. Silica is a colorless, odorless, and tasteless solid that is insoluble in water and most organic solvents. It has a high melting point and excellent thermal stability, making it useful in high-temperature applications. Silica exhibits a range of physical properties, including high hardness and brittleness, and it is a poor conductor of electricity. In addition to its geological significance, silica is widely used in various industries, including construction, electronics, and food production, often as a filler, abrasive, or desiccant. It is also an essential component in the manufacture of glass and ceramics. While generally considered safe, inhalation of fine silica dust can pose health risks, leading to respiratory issues such as silicosis.
