Embodiment 1

[0034] Example 1, such as Figure 1-3 Shown:

[0035] A kind of guided mode processing method of sheet-shaped sapphire, comprises the steps:

[0036] (1) Raw material processing: The raw material is first ultrasonically cleaned with acetone for 20 minutes, then ultrasonically cleaned with absolute ethanol for 10 minutes, and then ultrasonically cleaned with deionized water for 10 minutes to clean the raw material; Dry in an oven at 120°C for 1h to 1.5h, then soak the raw materials in concentrated hydrochloric acid with a mass fraction of 36%-38% for 26h to 30h, place them in a clean water pool to rinse until neutral, and then put them into a quartz crucible Dry for 1h~2h;

[0037] (2) Cleaning of the furnace body: before processing the flake sapphire with the guide mold, the furnace body shall be strictly inspected first to know whether there are foreign objects or sundries inside the furnace body by means of inspection, and the sundries inside the furnace body shall be clea...

Abstract

The invention relates to the technical field of sapphire processing, in particular to a guide mode processing method for flaky sapphire. The guide mode processing method mainly comprises the following steps: (1) treating raw materials; (2) cleaning a furnace body; (3) filling the raw materials; (4) vacuuming the furnace body; (5) performing high-temperature crystal guidance; (6) performing necking down; (7) performing shoulder expansion; (8) performing equal-diameter growth; and (9) performing annulling cooling, and the like. On one hand, impurities in the crystal growth process can be reduced, crystal can be prevented from being polluted, and the purity of the crystal can be improved; and on the other hand, bubbles generated in the melting process of the crystal can be reduced, raw material gaps can be reduced as the raw materials are compacted and filled according to a certain ratio, the bubble generation probability in crystal growth can be reduced, and the crystal quality can be improved; furthermore, through procedures of high-temperature crystal guidance, necking down, shoulder expansion, equal-diameter growth and annealing cooling, cracks, displacement, glass fragment strips and genetic defects can be reduced in the crystal growth process, and thus the crystal quality can be improved.

Description

technical field [0001] The invention relates to the technical field of sapphire processing, in particular to a guided-mode processing method for flaky sapphire. Background technique [0002] The English name of sapphire is Sapphire, which comes from the Latin Spphins, which means blue; it belongs to the corundum group of minerals and has a trigonal crystal system. In the gem world, all kinds of gem-quality corundum other than ruby ​​are called sapphires. Sapphires and rubies, emeralds, bodhi tourmalines, and tanzanites all belong to the genus of colored gemstones. [0003] Because corundum contains trace elements such as iron (Fe) and titanium (Ti), it presents blue, sky blue, light blue and other colors, among which bright sky blue is the best. The mineral name of sapphire is corundum, which belongs to the corundum group of minerals. In fact, gem-grade corundum in nature is called sapphire except for the red one called ruby, and other colors such as blue, light blue, gre...
