An amber aluminosilicate glass

Abstract

The invention discloses a piece of amber alumina silicate glass. The amber alumina silicate glass is characterized by also comprising the following components: 0.06%-0.3wt.% of WO3, and 0.2%-0.5wt.% of SO3. The invention also provides a preparation method for the amber alumina silicate glass. The preparation method comprises the following steps of adding 0.001wt.%-0.05wt.% of tungsten disulfide and 0.1wt.%-5wt.% calcium sulphide, relative to the total amount of batch, into the batch of normal alumina silicate glass so as to form the batch of the amber alumina silicate glass, and preparing the amber alumina silicate glass according to a known technology, wherein the melting temperature is 1630-1680 DEG C, the glass mold temperature is 1580-1620 DEG C, and the annealing temperature is 660-680 DEG C. The prepared amber alumina silicate glass comprises no harmful components, and has less environment pollution.

Description

technical field

[0001] The invention relates to a batch material for preparing amber aluminosilicate glass and a preparation method thereof, belonging to the field of colored glass preparation, in particular to a batch material obtained by adding tungsten disulfide and calcium sulfide, which is used to obtain aluminosilicate glass Amber glass tinted in a salt glass body. Background technique

[0002] Traditional amber glass is obtained by adding cadmium and selenium to the glass body, but cadmium and selenium are harmful to the environment and even banned by legislation in some countries. There are also some colored glasses obtained by coating or spraying a layer of varnish or raw lacquer with organic pigments on the surface of ordinary plain white or ultra-white glass, but this method has defects because the quality and durability of the coating will deteriorate over time. Aging and thermal shock will also cause the coating to peel off, and the color will naturally fade ac...
