Abstract

The invention discloses a preparation method for light blue crystal bead blanks. The preparation method for light blue crystal bead blanks aims to overcome shortcomings that existing preparation process for light blue crystal bead blanks is poor in coloring reproducibility, low in production efficiency and unsuitable for production operation of a continuous tan furnace, and the quality of products is unstable. The preparation method for light blue crystal bead blanks is fine in coloring reproducibility, high in production efficiency and applicable to production operation of a continuous furnace tank, and the quality of products is stable. In the preparation method for light blue crystal bead blanks, raw materials of the light blue crystal bead blanks include, by weight ratio, from 50 to 70 parts of quartz sand, from 3 to 15 parts of soda, from 4 to 16 parts of potassium carbonate, from 2 to 9 parts of potassium nitride, from 1 to 5 parts of boric acid, equal to or lower than 14 parts of lead silicate, equal to or lower than 3 parts of antimony trioxide, equal to or lower than 10 parts of barium carbonate, equal to or lower than 5 parts of titanium dioxide, equal to or lower than 3 parts of zinc oxide and equal to or lower than 2 parts of cobalt oxide.

Description

technical field [0001] The invention relates to the field of artificial crystal products, in particular to a method for preparing light blue crystal bead embryos. Background technique [0002] Light blue crystal bead embryos are semi-finished products used to prepare light blue crystal products. In the existing preparation process of light blue crystal bead embryos, cobalt ions are used for coloring. Cobalt ions are provided by cobalt oxide. The products produced by the color crystal bead embryo process generally have the disadvantages of poor coloring reproducibility, unstable product quality, low production efficiency, and are not suitable for continuous tank kiln production operations. In addition, in the existing technology for preparing light blue crystal bead embryos, there is red lead component in the raw material formula of light blue crystal bead embryos, and red lead is volatile and will cause environmental pollution. Contents of the invention [0003] The purpo...
