Method for preparing erbium-containing red glass

Abstract

The invention relates to a method for preparing erbium-containing red glass, which comprises the following steps of: firstly, mixing P2O5, BaO, Al2O3, Er2O3, CeO2 and Fe2O3 uniformly, and then melting the mixture to obtain glass liquid; secondly, performing water quenching on the glass liquid, and then drying and performing ball milling to be 50 meshes to obtain coloring agent glass; thirdly, after mixing P2O5, BaO, Al2O3, Fe2O3 and the coloring agent glass uniformly, melting the mixture; pouring the bubble-free molten glass liquid into a metal mould for molding; fourthly, placing the molded glass sample into a muffle furnace at the temperature of 450 DEG C for 3 hours, raising the temperature to be 600 DEG C at the speed of 20 DEG C per minute and preserving the heat for 1 hour; and finally, cooling the glass sample to room temperature at the speed of between 0.5 and 1 DEG C per minute to obtain the erbium-containing red glass. The erbium-containing red glass is prepared by a high temperature melting method; the method has the advantages of simple operation procedure, low melting temperature, low cost, energy conservation, environmental protection and suitability for industrial production; and the erbium-containing red glass prepared by the method has the advantages of high chemical stability, uniform coloring, high light transmittance and stable product quality.

Description

technical field [0001] The invention relates to a preparation method of red glass, in particular to a preparation method of erbium-containing red glass. Background technique [0002] With the improvement of people's living standards, colored glass has attracted more and more attention. Red glass is especially favored by consumers for its vivid color. The red glass that can be prepared by high temperature melting method includes: bright red selenium cadmium red glass, dark red copper red glass, rose red gold red glass, violet red neodymium red glass, pink erbium red glass, cherry red antimony red glass. So far, the production technology of cadmium selenium red glass is the most mature, the production is the most stable, and the application is the most extensive. Although the cadmium selenium red glass is bright in color, due to the cadmium contained in the glass, according to the Waste Electrical and Electronic Equipment (WEEE) promulgated by the European Union countries, ...
