Uku hiko, uku pai, pūnga iahiko, wae ngaruiti, uku hanga, aha atu

Ko te konupora zirconate (CaZrO3) te paura i synthesized ma te whakamahi i te konupūmā pūhaumāota (CaCl2), te konutai warowaihā (Na2CO3), me te zirconia (ZrO2) paura. I runga i te whakamahana, ka tauhohe a CaCl2 me Na2CO3 hei hanga NaCl me CaCO3. NaCl–Na2CO3 tote rewa i homai he reo tauhohenga wai mo te hanganga o CaZrO3 mai i te CaCO3 (CaO ranei) me ZrO2. I timata te CaZrO3 ki te hanga i te 700°C, ka piki ake te rahi me te piki haere o te pāmahana me te wa tauhohenga, me te heke haere o te CaCO3 (CaO ranei) me te ZrO2 kei roto. I muri i te horoinga me te wai wera-wera, ko nga tauira i whakamahanahia mo te 5 h i te 1050 ° C he waahanga kotahi CaZrO3 me te rahi o te witi 0.5-1.0 μm.
