Tin dioxide is a chemical compound made up of tin and oxygen, with the formula SnO2. It appears as a white powder and is commonly used in various applications, including electronics, ceramics, and as a catalyst in chemical reactions. Its properties make it useful for creating transparent conductive coatings and in the production of glass. In addition to its industrial uses, tin dioxide is also employed in the manufacturing of certain types of sensors and solar cells. Its ability to conduct electricity while remaining transparent makes it valuable in technologies that require both conductivity and visibility.
