Abstract

The invention discloses a preparation method of polycrystalline zirconium gemstone. A specific embodiment of the method comprises the following steps: adding zirconium oxychloride into purified water for complete dissolution to obtain a zirconium oxychloride solution; generating a zirconium sulfate solid based on the zirconium oxychloride solution and sodium sulfate; dissolving the zirconium sulfate solid in purified water, adding yttrium chloride and a magnesium chloride solution, and mixing to obtain a mixed solution; adding an alkali solution into the mixed solution to completely separate out a solid precipitate; carrying out drying and pre-sintering treatment on the solid precipitate; introducing purified water, a coloring agent, a water-soluble organic dispersant, a water-soluble polymer stabilizer and the pre-sintered substance into a ball mill filled with aluminum oxide grinding balls, and carrying out homogenization grinding treatment to obtain a mixed suspension; and carrying out spray drying treatment on the mixed suspension to obtain the polycrystalline zirconium gem material. According to the embodiment, the hardness of the prepared zirconium gem is improved.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of preparation of zircon gemstones, in particular to methods for preparing polycrystalline zircon gemstones. Background technique [0002] At present, zirconia is widely used in refractory materials, abrasive tools, solid fuel cells, jewelry and other fields. The preparation of zirconia usually adopts the cold crucible method. [0003] However, with the above-mentioned preparation method, the following technical problems usually exist: [0004] First, the hardness of zirconia (zirconium gem) prepared by the cold crucible method is low; [0005] Second, the zirconia prepared by the cold crucible method has a single color. Contents of the invention [0006] The Summary of the Disclosure is provided to introduce concepts in a simplified form that are described in detail in the Detailed Description that follows. The content of this disclosure is not intended to identify the key features or...
