Calcium zirconate (CaZrO3) budada waxaa lagu farsameeyay iyadoo la isticmaalayo kaalshiyam chloride (CaCl2), sodium carbonate (Na2CO3), iyo zirconia (ZrO2) budada. Kuleylinta, CaCl2 waxay la falgashay Na2CO3 si ay u sameyso NaCl iyo CaCO3. NaCl–Na2CO3 cusbada dhalaalaysa waxay siisay dhexdhexaad falcelin dareere ah samaynta CaZrO3 ee goobta ku samaysan CaCO3 (ama CaO) iyo ZrO2. CaZrO3 waxa ay bilowday in ay samayso ku dhawaad 700°C, iyada oo kordhinaysa qadarka heerkulka korodhay iyo wakhtiga falcelinta, iyada oo hoos u dhac ku yimi CaCO3 (ama CaO) iyo waxa ku jira ZrO2. Ka dib markii lagu dhaqay biyo kulul oo kulul, shaybaarada lagu kululeeyay 5 h at 1050 ° C waxay ahaayeen hal weji CaZrO3 oo leh 0.5-1.0 μm xajmi hadhuudh ah.
