preparation example Construction

[0034] A method for preparing stone-like glass-ceramics, the raw materials are configured according to requirements, the raw materials are passed into the melting part, mixed and then melted to form molten glass, and then the glass liquid is passed into the cooling part, homogenized, clarified and discharged in the cooling part bubbles, and then discharge the molten glass to the forming part, anneal after forming, and finally make stone-like glass-ceramic, wherein the temperature in the forming part is kept at 1320 ° C to 1400 ° C, and the time for the glass liquid to be stored in the forming part is 1 to 10 hours. After cooling down, annealing after forming, and finally made into stone-like glass-ceramics. The heat preservation process of the forming part is conducive to the growth of crystal nuclei. Since the raw material may stick in the mold cavity during the crystallization process, the mold cavity needs to be destroyed, so the mold cavity can be made of low-cost heat-re...

Abstract

The invention discloses red stone-imitating microcrystalline glass. According to the red stone-imitating microcrystalline glass, silicon, calcium, lithium, magnesium and barium are used as main components, rare earth metals are used for improving performance, and erbium oxide and gold chloride are used as colorants. The molded red stone-imitating microcrystalline glass is low in light transmittance and red in color, and the strength and hardness of the red stone-imitating microcrystalline glass can meet needs, so that the red stone-imitating microcrystalline glass can be used for imitating red jewelries. The harness of the red stone-imitating microcrystalline glass is close to 650Kg/mm<2>, the density of the red stone-imitating microcrystalline glass is close to 3g/mm<3>, and the harness and density of the red stone-imitating microcrystalline glass are close to those of the red jewelries.

Description

technical field [0001] The invention relates to artificial ruby, in particular to red stone-like glass-ceramics and a preparation method thereof. Background technique [0002] Glass-ceramic is mainly composed of silicon, aluminum, calcium, potassium, sodium and other components. In order to adjust its color, coloring agents such as copper, iron, and chromium are often added to it. In order to imitate the gloss and hardness of jewellery, multiple colorants are often used simultaneously in the prior art. [0003] 201310384986.2 relates to a deep red infrared-transmitting quartz glass plate, which contains trace components, the trace components include copper oxide CuO0.15-0.3 parts, manganese dioxide MnO21-2.5 parts, samarium oxide SmO2-4 parts, aluminum oxide al 2 o 3 1.5-2.5 parts, cobalt chloride CoCl 2 ·6H 2 O0.03-0.05 parts, erbium oxide Er 2 o 3 0.2-0.8 parts. The glass plate is dark red and clear. [0004] 201010256101.7 relates to a preparation method of coppe...
