Preparation method for modena crystal bead blank

Abstract

The invention discloses a preparation method for a modena crystal bead blank. The invention provides a preparation method, which has the advantages of good coloring reproducibility, stable product quality and high production efficiency and can be suitable for the production operation of a continuous tank furnace, for a modena crystal bead blank by aiming at the defects of poor coloring reproducibility, unstable product quality, low production efficiency and inadequacy for the production operation of a continuous tank furnace of the traditional technology for preparing the modena crystal bead blank. According to the preparation method for a modena crystal bead blank, the modena crystal bead blank is prepared from the following raw materials in parts by weight: 50-70 parts of quartz sand, 5-15 parts of soda ash, 4-16 parts of potassium carbonate, 2-9 parts of nitrate of potash, 2-6 parts of boric acid, 4.5-6 parts of potassium permanganate, less than or equal to 10 parts of lead silicate, less than or equal to 7 parts of aluminium hydroxide, less than or equal to 3 parts of calcium carbonate, less than or equal to 1 part of lithium carbonate 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 deep purple crystal bead embryos. Background technique [0002] Deep purple crystal bead embryos are semi-finished products used to prepare deep purple crystal products. In the existing process of preparing deep purple 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. In addition, in the existing technology for preparing deep purple crystal bead embryos, there is red lead component in the raw material formula of deep purple crystal bead embryos, and red lead is volatile and will cause environmental pollution. Contents of the invention [0003] The purpose of the...
