Zirconium Hydroxide High Purity 99.9% 20-30nm For Catalyst Carrier

White amorphous powder, non-toxic and tasteless, insoluble in water, soluble in hydrochloric acid 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 ammonia water as raw materials to prepare zirconium hydroxide: Under stirring at room temperature, pure ammonia 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 ℃.

2. Made from sodium hydroxide solution and zirconium salt solution.
