Abstract

The invention relates to a preparation method of Zr-P fluoride-free opaque glass, comprising the following steps: 1) using the following ingredients comprising 63-73 weight portions of silica, 5.0-8.0 weight portions of alumina, 8.0-12.0 weight portions of calcium oxide, 2.0-5.0 weight portions of magnesium oxide, 1.0-2.0 weight portions of barium oxide, 1.0-3.0 weight portions of lithium oxide, 10.0-15.0 weight portions of sodium oxide, 0.5-1.0 weight portions of boron oxide, 2.0-6.0 weight portions of phosphoric pentoxide, 2.0-5.0 weight portions of zirconia and 0.5-1.0 weight portions of clarificant; 2) controlling the glass melting temperature within 1530-1550 DEG C and the cooling temperature within 1280-1350 DEG C; 3) molding the raw materials; 4) putting the molded opaque glass in a crystallization kiln for heat treatment; and 5) cooling the opaque glass processed by micritization until the annealing high-limit temperature reaches 580-600 DEG C, then carrying out annealing, so as to obtain the Zr-P fluoride-free opaque glass after annealing. The Zr-P fluoride-free opaque glass has the characteristics of uniform phase separation and delicate structure.

Description

technical field [0001] The invention relates to a preparation method of zirconium phosphorus fluorine-free opaque glass. It is especially suitable for the production of opal glass tableware, art and architectural decoration products. The opal glass tableware and other products prepared by this method have the characteristics of fine texture, soft color, high purity and elegance. Background technique [0002] Opalescent glass refers to a special glass material that contains a large amount of highly dispersed phases. Because its refractive index is different from that of the main glass, it will scatter light after being irradiated with light, and present a special glass material that is opalescent. The formation mechanism of glass opacification mainly includes grain opacification, phase separation opacification, unmelted particle opacification and micro-bubble opacification. According to the different opacifiers used, opacified glass mainly includes fluoride opacified glass, ...
