Smoke yellow crystal bead blank and preparation method thereof

Abstract

The invention discloses a smoke yellow crystal bead blank and a preparation method thereof. The smoke yellow crystal bead blank is prepared from the following components in parts by weight: 90-165 parts of quartz sands, 11-19 parts of zinc oxide, 28-53 parts of sodium carbonate, 15-30 parts of potassium carbonate, 5-17 parts of boric acid, 3-5 parts of calcium carbonate,0.8-3.2 parts of aluminum hydroxide, 1-2 parts of table salt, 2-5 parts of antimonous oxide, 0.1-2 parts of potassium nitrate, 0.01-0.15 part of sodium selenite, 0.001-0.003 part of ferrous sulfide, 0.1-0.8 part of samarium oxide and 0.9-2.2 parts of nickel oxide. When the smoke yellow crystal bead blank is prepared, a lot of cerous compounds are not used, colors of selenium and compounds of selenium are fixed in secondary finishing, and the bead blank is adjusted to smoke yellow by virtue of compounds of samarium and nickel. Lead-containing raw materials are not used, and the bead blank has the advantages of good glossiness, bright color, orderliness, no chromatic aberration and patterns, high yield, no lead and pollution, and good production benefit.

Description

technical field [0001] The invention relates to a smoky yellow crystal bead embryo and a preparation method thereof. Background technique [0002] Smokey yellow crystal bead embryos are semi-finished products used to prepare smokey yellow crystal products. The existing smokey yellow crystal bead embryos are manufactured in a crucible, which has poor coloring, uneven colors, patterns, unstable product quality, and low production efficiency. It is not suitable for continuous mass production, and burning with coal causes environmental pollution. Moreover, some of the existing process formulas consume expensive rare earth erbium oxide, some are colored with selenium powder but are unstable, and some contain lead compounds that pollute the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a smoky yellow crystal bead embryo with good coloring reproducibility, consistent color, no color difference, no patter...
