Abstract

The invention discloses a composition and a production method of gold colloid colored fusible gold ruby glass adopting bismuth borosilicate glass as a matrix. The composition of the fusible gold ruby glass comprises 0-10 wt% of Na2O, 0-15 wt% of K2O, 0-2 wt% of Li2O, 10-60 wt% of Bi2O3, 2-15 wt% of B2O3, 25-50 wt% of SiO2, 0-5 wt% of ZnO, 0-3 wt% of Al2O3, 0.5-3 wt% of Sb2O3, 0.5-1.5 wt% of SnO and 0.01-0.1 wt% of Au. Compared with lead-containing fusible gold ruby glass produced through traditional methods, the gold ruby glass produced in the invention has similar spectral properties and good chemical stability. The colloid colored glass produced in the invention has beautiful color and very good practical application prospect; and bismuth oxide replaces lead oxide to avoid pollution to the environment and damages to organisms during the use process, so the "green production" requirement is met.

Description

technical field [0001] The present invention relates to a R 2 O-Bi 2 o 3 -B 2 o 3 -SiO 2 A preparation method for preparing rose red glass by doping gold colloidal colorant in systematic glass. Background technique [0002] Colored glass is widely used in art decoration, light filtering, lighting, signal, laser and fluorescence, etc. It is of great significance to people's daily life, industrial and agricultural production, scientific culture and national defense construction. Red glass is favored by everyone because of its unique charm. Colloidal tinted glass has attracted much attention because of its gorgeous color, but most colloidal tinted glass uses lead glass as the base glass, because lead glass can dissolve metal elements better. However, lead will pollute the environment and cause harm to organisms, so it is of great significance to develop lead-free glass that is harmless to the environment and human body. Contents of the invention [0003] What the pres...
