A kind of crystal bead embryo of light bright red color and preparation method thereof

Abstract

The invention discloses a shallow bright red crystal bead embryo and its preparation method, the shallow bright red crystal bead embryo is composed of the following components by weight: 120-230 parts of quartz sand, 15-40 parts of zinc oxide, 30-90 parts of sodium carbonate, 15-45 parts of potassium carbonate, 10-30 parts of boric acid, 2-12 parts of calcium carbonate, 0.5-4 parts of aluminum hydroxide, 1-5 parts of salt, 3-3.5 parts of cadmium yellow, 0.5-3 parts of selenium powder and 0.5-8 parts of cadmium red. The good coloring property can be obtained by maintaining redox equilibrium of copper ions in the melting process stable during preparation of the shallow bright red crystal bead embryo, lead-containing materials are not used, and the shallow bright red crystal bead embryo has the advantages of good glossiness, bright and neat color, no color difference, no pattern, high yield, no lead, no pollution, and good production benefit.

Description

technical field [0001] The invention relates to a light red color crystal bead embryo and a preparation method thereof. Background technique [0002] Light red color crystal bead embryos are semi-finished products used to prepare light red color crystal products. The existing light red color crystal bead embryos process is made in a crucible, which has poor coloring, uneven colors, patterns, and unstable product quality. The efficiency is low, it is not suitable for continuous mass production, and the burning of coal causes environmental pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of bright red crystal bead embryo with good coloring reproducibility, consistent color, no color difference, no pattern, stable product quality, high production efficiency, and suitable for continuous tank kiln production operations. [0004] In order to solve the above problems, the present invention is achieved ...
