Zirconia, yomwe imadziwikanso kuti zirconium dioxide, nthawi zambiri imakonzedwa pogwiritsa ntchito njira yotchedwa "njira yopangira ufa." Izi zikuphatikizapo njira zingapo, kuphatikizapo:
1. Calcining: Kutenthetsa zirconium mankhwala mpaka kutentha kwambiri kupanga zirconium oxide ufa.
2. Akupera: Pogaya calcined zirconia kukwaniritsa kufunika tinthu kukula ndi kugawa.
3. Kujambula: Pansi pa zirconia ufa umapangidwa kuti ukhale wofunidwa, monga ma pellets, midadada kapena mawonekedwe achikhalidwe, pogwiritsa ntchito njira monga kukanikiza kapena kuponyera.
4. Sintering: Zirconia zooneka ngati sintered pa kutentha kwambiri kukwaniritsa chomaliza wandiweyani kristalo dongosolo.
5. Kumaliza: Sintered zirconia akhoza kukumana njira zina processing monga akupera, kupukuta ndi Machining kukwaniritsa kufunika pamwamba mapeto ndi kulondola dimensional.
Njirayi imapereka mankhwala a zirconia kumphamvu kwambiri, kuuma komanso kukana kuvala, kuwapanga kukhala oyenera kugwiritsa ntchito zosiyanasiyana m'mafakitale monga zakuthambo, zamankhwala ndi zomangamanga.
Zircon ndi mchere wa zirconium silicate womwe umagwiritsidwa ntchito pophatikiza kuphwanya, kugaya, kupatukana kwa maginito ndi njira zolekanitsa mphamvu yokoka. Pambuyo potulutsidwa mu ore, zircon imakonzedwa kuti ichotse zonyansa ndikuzilekanitsa ndi mchere wina. Izi zimaphatikizapo kuphwanya miyalayo mpaka kukula bwino ndikuipera kuti muchepetse kukula kwake. Kulekanitsa maginito kumagwiritsidwa ntchito kuchotsa mchere wa maginito, ndipo teknoloji yolekanitsa mphamvu yokoka imagwiritsidwa ntchito kulekanitsa zircon ndi mchere wina wolemera. Zotsatira za zircon concentrate zitha kuyengedwanso ndikusinthidwa kuti zigwiritsidwe ntchito m'mafakitale osiyanasiyana.
Zida zopangira zirconium nthawi zambiri zimaphatikizapo mchenga wa zircon (zirconium silicate) ndi baddeleyite (zirconia). Mchenga wa Zircon ndiye gwero lalikulu la zirconium ndipo amakumbidwa kuchokera ku mchere wamchenga. Baddeleyite ndi mawonekedwe achilengedwe a zirconium oxide ndipo ndi gwero lina la zirconium. Zopangira izi zimakonzedwa kuti zichotse zirconium, zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo kupanga zirconium zitsulo, zirconium oxide (zirconia) ndi mankhwala ena a zirconium.
