Glass no toxic cadmium, vitrified red or yellow inorganico, process to prepare a glass no toxic cadmium and process to prepare a vitrified red and yellow inorganico

摘要

A cadmium glass is disclosed which comprises (weight percent) CdO 10-50, TiO2 0-30, ZrO2 0-30, SiO2 10-60 and Al2O3 0-10. The glass is a highly concentrated source of cadmium with relatively low cadmium oxide solubility or release, as when ingested in the human system, to render it essentially nontoxic and thereby adapted for many applications. A chief use for the nontoxic cadmium glass is as a stabilizer for inorganic red or yellow glazes. Cadmium oxide solubilities as low as 0.0% are possible, depending on particle size of the ground glass.
