Title: Ammonium Zirconyl Carbonate
CAS Registry Number: 12616-24-9
Additional Names: Ammonium tricarbonatozirconate
Molecular Formula: C3H13N3O10Zr
Molecular Weight: 342.37
Percent Composition: C 10.52%, H 3.83%, N 12.27%, O 46.73%, Zr 26.64%
Line Formula: (NH4)3ZrOH(CO3)3
Literature References: Prepd from ZrO2CO2.8H2O, NH4HCO3 and (NH4)2CO3: Blumenthal, J. Chem. Educ. 39, 604 (1962).
Derivative Type: Dihydrate
Properties: Large prisms from water. Unstable in air, gradually evolving carbon dioxide and ammonia. Sol in water. Marketed as aq soln: d2424 1.238. The aq soln is moderately stable at room temp, although, after standing a month or so, it is likely to deposit hydrous zirconia. At temps above 60° aq solns dec rapidly.
Density: d2424 1.238
Use: Water-repellent. Leaves a zirconium residue after the evaporation of ammonia and carbon dioxide, without leaving other cations or anions. |
