• Ammonium zirconium carbonate • Ammonium tetrahydroxyzirconate(IV) carbonate • Zirconyl carbonate diammonium salt • AZC • Diammonium zirconium(IV) carbonate Ammonium zirconium carbonate (AZC) is an inorganic chemical compound with the formula (NH4)2Zr(CO3)2·xH2O. It is the double salt of ammonium carbonate and zirconium carbonate and appears as a white crystalline powder. It is produced by reacting ammonium carbonate with zirconyl chloride or zirconyl sulfate.AZC is stable in dry air but slowly hydrolyzes in moist air. It is insoluble in ethanol but soluble in water and liquid ammonia. Aqueous solutions are alkaline.AZC is an important intermediate compound used in the production of zirconium-based ceramics, glazes, enamels, and coatings. Upon heating above 70°C, AZC first loses ammonia and water molecules to form ZrOCO3. Further heating to high temperatures leads to the decomposition into zirconium dioxide (zirconia, ZrO2) and carbon dioxide (CO2). |
