Preparation method of army green crystal bead embryos

Abstract

The invention relates to a preparation method of army green crystal bead embryos. The invention aims at providing the preparation method of the army green crystal bead embryos which has the advantages of no use of lead oxide in raw materials, good physical and chemical properties of the crystal bead embryos, appropriate hardness and strong corrosion resistance against the problems that a conventional preparation process of the army green crystal bead embryos needs to adopt the lead oxide in the raw materials, the physical and the chemical properties of the crystal bead embryos are poorer, iron ions are used in the process for coloration, and the coloration optical performance of the iron ions is poor. According to the preparation method of the army green crystal bead embryos, disclosed by the invention, the mixture ratio of the raw materials of the army green crystal bead embryos by weight is as follows: the army green crystal bead embryos comprise 50-65 parts of quartz sand, 2-20 parts of titanium dioxide, 2-10 parts of sodium carbonate, 8-15 parts of potassium carbonate, 2-6 parts of potassium nitrate, 0.1-5 parts of cerium oxide, not more than 6 parts of boric acid, not more than 2 parts of chromium oxide green, not more than 8 parts of zinc oxide, not more than 15 parts of lead silicate, not more than 15 parts of barium carbonate and not more than 2 parts of antimony trioxide.

Description

technical field [0001] The invention relates to the field of artificial crystal products, in particular to a method for preparing army green crystal bead embryos. Background technique [0002] Army green crystal bead embryo is the semi-finished product that is used to prepare army green crystal product, exists following weak point in existing preparation army green crystal bead technology: [0003] 1. In order to achieve a higher refractive index, red lead must be used in the raw materials, which is known to cause environmental pollution; [0004] 2. The physical and chemical properties of crystal bead embryos are not good, the hardness is either too high or too low, and the corrosion resistance is poor; [0005] 3. In the preparation process, iron ions are used for coloring, which has poor product performance, unsatisfactory color light and poor effect, and the iron content of the raw material quartz sand is required to be less than 0.05%, and the quartz sand with low iron...
