Description

Technical Field

[0001] This utility model relates to the field of zirconia hydrolysis tanks, and in particular to a hydrolysis mechanism for processing zirconia powder. Background Technology

[0002] Zirconium dioxide, or zirconium oxide for short, is produced by hydrolysis of zirconium salt precursors in water. The precursors are dissolved in water and hydrolyzed to form zirconium hydroxide precipitate by controlling the pH and temperature. After washing, drying, and calcination, zirconium dioxide powder is obtained.

[0003] During the processing of zirconium dioxide powder, harmful gases are generated during hydrolysis. When zirconium oxychloride is used as a precursor, hydrogen chloride gas is released during hydrolysis; when zirconium nitrate is used as a precursor, nitrogen dioxide gas is released during hydrolysis; and the sol-gel method of zirconium alkoxide releases alcohol gases during hydrolysis.

[0004] During the processing of zirconium dioxide powder, the harmful gases produced during the hydrolysis process are either harmful to the human body or pose a risk of combustion and explosion. If they are directly emitted without purification, they will damage the environment and easily harm the human body. Therefore, a hydrolysis mechanism for processing zirconium dioxide powder is proposed. Utility Model Content
