Abstract

The invention discloses a preparation method of a large black crystal bead semi-finished product. The preparation method solves the problem that the existing preparation method of a large black crystal bead semi-finished product has poor coloring reproducibility, produces instability of product quality, has low production efficiency and is not suitable for production in continuous tank furnaces. The preparation method provided by the invention has good coloring reproducibility, realizes stable product quality, has high production efficiency and is suitable for production in continuous tank furnaces. The large black crystal bead semi-finished product obtained by the preparation method comprises: by weight, 50 to 70 parts of quartz sand, 7 to 18 parts of soda ash, 3 to 18 parts of potassium carbonate, 8 to 17 parts of hydrated borax, less than or equal to 2 parts of sodium chloride, less than or equal to 10 parts of manganese dioxide, less than or equal to 3 parts of aluminum hydroxide, less than or equal to 2 parts of nickel oxide, less than or equal to 5 parts of barium carbonate, less than or equal to 5 parts of potassium dichromate and less than or equal to 3 parts of magnesium carbonate.

Description

technical field [0001] The invention relates to the field of artificial crystal products, in particular to a method for preparing large black crystal bead embryos. Background technique [0002] Big black crystal bead embryos are semi-finished products used to prepare big black crystal products. In the existing process of preparing big black crystal bead embryos, manganese ions are used for coloring. Manganese ions are provided by manganese dioxide. The products produced by 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. Contents of the invention [0003] The purpose of the present invention is to provide a method for the disadvantages of poor coloring reproducibility, unstable product quality, low production efficiency, and unsuitability for continuous tank kiln production operations in the existing technology for prepar...
