White amorphous powder, non-toxic and tasteless, insoluble in water, soluble in HCl and other inorganic acids. Insoluble in water and alkali solutions, it decomposes into zirconium dioxide and water at 500 ° C.

1. The neutralization method uses zirconium oxychloride and NH3 water as raw materials to prepare zirconium hydroxide: Under stirring at room temperature, pure NH3 water is slowly added into 0.2 ~ 0.3 mol/L high purity zirconium oxychloride solution, and the solution is neutralized until pH = 8 ~ 8.5, and then washed with pure water until no chloride ion (Cl-) is present. The product is obtained after filtration and separation, and the cake is dried at 120 ºC.

2. Made from NaOH solution and zirconium salt solution.

Zirconium hydroxide is a kind of water insoluble, slightly more alkaline amphoteric hydroxide, the appearance of white powder solid, widely used in various chemical industries.

Application 

Used in lithium manganate, lithium cobalt acid, lithium iron phosphate, ternary materials and other lithium battery cathode materials. Used in the manufacture of other zirconium compounds, pigments, dyes, glass, etc.
