Abstract

The invention discloses a preparation method for a transparent black crystal ball blank, and provides the preparation method for the transparent black crystal ball blank aiming at the defects of low coloring repeatability, product quality and production efficiency in the conventional preparation method for the transparent black crystal ball blank, and the defect that the conventional preparation method for the transparent black crystal ball blank is not suitable for continuous production operation of a tank furnace. By the method, a product is high in coloring repeatability, and stable in quality; and the method is high in production efficiency and suitable for continuous production operation of the tank furnace. According to the preparation method for the transparent black crystal ball blank, the transparent black crystal ball blank is prepared from the following raw materials in part by weight: 50 to 70 parts of quartz sand, 5 to 15 parts of sodium carbonate, 4 to 16 parts of potassium carbonate, 2 to 9 parts of potassium nitrate, 2 to 6 parts of boric acid, less than or equal to 10 parts of lead silicate, less than or equal to 3 parts of aluminum hydroxide, less than or equal to 4 parts of calcium carbonate, less than or equal to 2 parts of lithium carbonate, less than or equal to 5 parts of erbium oxide, less than or equal to 3 parts of chrome oxide green, less than or equal to 3 parts of magnesium carbonate, and less than or equal to 5 parts of nickel oxide.

Description

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