Lead (II) oxide, also called lead monoxide, is an amphoteric oxide. Modern applications for lead (II) oxide are mainly in industrial glass and ceramics, including the components of electronic device. In the production of industrial glass and ceramics, the benefits of using Lead (II) oxide include increasing the refractive index, the electrical resistivity, the X-rays absorption capacity, magnetism, and decreasing the viscosity. The processing of Lead (II) oxide is the key component of automotive lead-acid batteries, so it is also widely used in automotive industry.
