Calcium zirconate (CaZrO3) poda yakashandiswa kushandisa calcium chloride (CaCl2), sodium carbonate (Na2CO3), uye zirconia (ZrO2) powders. Pakupisa, CaCl2 yakaita neNa2CO3 kugadzira NaCl neCaCO3. NaCl–Na2CO3 yakanyungudutswa munyu yakapa svikiro rekuita mvura kuitira kuumbwa kweCaZrO3 kubva mu-situ-yakaumbwa CaCO3 (kana CaO) uye ZrO2. CaZrO3 yakatanga kuumbwa inosvika 700°C, ichiwedzera muhuwandu nekuwedzera tembiricha uye nguva yekuita, nekudzikira kwakafanana kweCaCO3 (kana CaO) neZrO2 zvirimo. Mushure mekugeza nemvura inopisa-yakasvibiswa, sampuli dzinopisa 5 h pa 1050 ° C dzaive imwe-phase CaZrO3 ine 0.5-1.0 μm saizi yezviyo.
