ABSTRACT:
UV absorbing glass is prepared by mixing ultrafine colloidal cerium oxide with glass-forming substances during the fabrication of the glass. An aqueous colloidal dispersion containing 1-20 weight percent 10-20 nm cerium oxide particles, optionally including a binder, is admixed with silica sand, and the sand is dried, melted and cooled to give a relatively clear UV absorbing glass containing 0.3-2 weight percent cerium oxide.
