Monoxide Monoxide A monoxide is any oxide containing just one atom of oxygen in the molecule. For example, Potassium oxide (KO), has only one atom of oxygen, and is thus a monoxide. Water (HO) is also a monoxide; see dihydrogen monoxide hoax. A well known monoxide is carbon monoxide (CO); see carbon monoxide poisoning. Most of the members of the Periodic Table form oxides when oxidized. There are two main types of oxides: monoxides and dioxides. Monoxides (generally MO) such as silicon monoxide (SiO) only exist at high temperatures. Among monoxides, CO is neutral, GeO is distinctly acidic, and SnO and
Tin(IV) Oxide °C) and in the presence of a combustible gas the electrical resistivity drops. Doping with various compounds has been investigated (e.g. with CuO). Doping with cobalt and manganese, gives a material that can be used in e.g. high voltage varistors. Tin(IV) oxide can be doped with the oxides of iron or manganese. Tin(IV) Oxide Tin(IV) Oxide, also known as stannic oxide, is the inorganic compound with the formula SnO. The mineral form of SnO is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is an important material in tin chemistry.
