Embodiment 1

[0017] The present invention proposes a kind of zirconia production technology, comprises the following steps:

[0018] S1: Choose zircon as the raw material, and perform multiple ultrasonic cleaning on the zircon to remove impurities on the surface of the zircon, and then dry it for later use;

[0019] S2: Put the zircon treated in S1 in a melting furnace, add caustic soda to the melting furnace, and melt it at 600 degrees Celsius. During the melting process, it needs to be mixed and stirred in real time to ensure that the zirconium Quartz and caustic soda are mixed evenly, and after the smelting is completed, the molten liquid is leached through hot water to form the first mixed liquid, which is ready for use;

[0020] S3: Place the first mixed liquid formed above in a stirrer, and lower its temperature to 300 degrees Celsius, then add sodium zirconate to it, and stir in real time, so as to separate the first mixed liquid, after the separation is completed , adding an acid ...

[0028] The present invention proposes a kind of zirconia production technology, comprises the following steps:

[0029] S1: Choose zircon as the raw material, and perform multiple ultrasonic cleaning on the zircon to remove impurities on the surface of the zircon, and then dry it for later use;

[0030] S2: Put the zircon treated in S1 in a melting furnace, add caustic soda to the melting furnace, and melt it at 625 degrees Celsius. During the melting process, it needs to be mixed and stirred in real time to ensure that the zircon Quartz and caustic soda are mixed evenly, and after the smelting is completed, the molten liquid is leached through hot water to form the first mixed liquid, which is ready for use;

[0031] S3: Place the first mixed liquid formed above in a stirrer, and lower its temperature to 330 degrees Celsius, then add sodium zirconate to it, and stir in real time, so as to separate the first mixed liquid, after the separation is completed , adding an acid sol...

Embodiment 3

[0039] The present invention proposes a kind of zirconia production technology, comprises the following steps:

[0040] S1: Choose zircon as the raw material, and perform multiple ultrasonic cleaning on the zircon to remove impurities on the surface of the zircon, and then dry it for later use;

[0041] S2: Put the zircon treated in S1 in a melting furnace, add caustic soda to the melting furnace, and melt it at 650 degrees Celsius. During the melting process, it needs to be mixed and stirred in real time to ensure that the zirconium Quartz and caustic soda are mixed evenly, and after the smelting is completed, the molten liquid is leached through hot water to form the first mixed liquid, which is ready for use;

[0042] S3: Put the first mixed liquid formed above in a stirrer, and lower its temperature to 375 degrees Celsius, then add sodium zirconate to it, and stir in real time, so as to separate the first mixed liquid, after the separation is completed , adding an acid so...

Abstract

The invention discloses a zirconia production process. The zirconia production process comprises the following steps of: placing zircon in a smelting furnace, adding caustic soda into the smelting furnace, performing real-time mixing and stirring on the mixture, leaching molten liquid by using hot water, putting first mixed liquid in a stirrer, then adding sodium zirconate into the stirrer, performing real-time stirring, then adding an acid solution into the stirrer to obtain second mixed liquid, performing impurity removal, putting the second mixed liquid which is subjected to impurity removal in a vessel again, performing mixing and stirring at 60-80 DEG C, adding a precipitating agent into the vessel while stirring is conducted, then placing treated zirconium hydroxide in the smelting furnace, performing second melting at 500-600 DEG C, and adding a catalyst into the solution to obtain the zirconia. Through the zirconia production process, not only can the quality of the zirconia beimproved, but also the melting point of the zirconia can be increased, so that the obtained zirconia is adaptive to different environments, and the needs of present development are met.

Description

technical field [0001] The invention relates to the technical field of zirconia preparation, in particular to a zirconia production process. Background technique [0002] Zirconia (ZrO 2 ) Natural zirconia mineral raw materials mainly include baddeleyite and zircon. Zircon is a deep mineral of igneous rocks, with colors of light yellow, brown yellow, yellow green, etc., specific gravity 4.6-4.7, hardness 7.5, strong metallic luster, and can be used as raw material for ceramic glazes. As zirconia is more or less used in all walks of life, more and more attention is paid to the quality of zirconia. In the prior art, only baddeleyite or zircon is preliminarily processed. It is directly used, which makes the quality of zirconia insufficient. To this end, we propose a zirconia production process. Contents of the invention [0003] The present invention proposes a zirconia production process to solve the problems raised in the background art above. [0004] The present inve...
