Lead glass, also known as medical X-ray radiation shielding lead glass, is primarily categorized into domestic and imported lead glass. It is mainly used in diagnostic X-ray rooms, CT, ECT, PET, CT-PEET rooms, as well as X-ray photography protective rooms and observation windows in protective doors and screens. The required thickness can be determined by calculation. It is used to manufacture optical glass, vacuum glass, low-temperature sealing glass, radiation shielding glass, lead quality glass, fire glass, low-melting glass, delay line glass, high-refractive pearl glass, and artistic ware glass, among others.
