Yakaomeswa zirconia corundum chidhinha chakagadzirwa nechena yealuminium oxide poda ine 65% zirconia uye 34% silica Zircon jecha rakachena chena rakaumbwa nekunyungudika mumagetsi inonyunguduka moto uye kutonhodza mune modhi. Chimiro chayo cheLithofacies chinoumbwa ne eutectoid uye girazi chikamu che corundum uye zirconia clinopyrite. Kubva pakuona kwema facies, ndiyo eutectoid ye corundum phase uye zirconia clinopyrite phase, uye chikamu chegirazi chinozadzwa pakati pemakristasi avo. Nekuda kwekuvapo kwechikamu chayo chegirazi, pasi pemamiriro ekugara kwenguva refu kupisa tembiricha, iyo girazi chikamu inopindura uye inosuka nezvimwe zvinhu mugirazi remvura, zvichikonzera kurasikirwa kwerwizi-chikamu kukwenya uye kunamatira kwegirazi chikamu , zvichikonzera kuvhurwa kwe porosity, uye kukoromoka uye kutsvaira pakati pe corundum ne zirconia clinopyrite nemhinduro uye yakaderera mhinduro, zvichikonzera kuwedzera kwekukuvara kwezvidhina, Corundum uye oblique zircon zvinoramba zvichirasika uye zvichirasika mugirazi gadziriso nekukukurwa uye kupera. Kana kukonzeresa uye kukosora kwasvika padanho (kana kukonzeresa kunokonzerwa neakanyanya-tembiricha anoshanda emakemikari maitiro), zvakafanira kumisa kugadzirwa uye kutsiva nyowani dziva remagetsi rinonyungudza zvidhinha, izvo kwete chete zvine mutengo wakakwira, asi zvakare zvine kurasikirwa kukuru kwe kudzima uye kugadzirisa, zvichikonzera kuoma kukuru kwemitengo yezvigadzirwa zvegirazi zvigadzirwa.

Iko kurwisa kwehurosi uye kuputika kweiyo yekushanda dura inosangana neye girazi mhinduro inovandudzwa nekuda kwekuwedzera kwe zirconia zvemukati, uye hupenyu hwebasa rezvinhu zvidhinha zvakaenzana zvakareba. Yakabatanidzwa pamwe nekuchengetedza kuchengetedzwa kwekuita kweiyo inodzivirira diki uye kupisa kupisa kudzikisira kuita kweye thermal kuputira dura, hupenyu hwebasa hwebira rinoshandisa chidhinha chinosungirwa kuvandudzwa, Kuvandudzwa kwehupenyu hwebasa kunoreva kuti simba rekushandisa rinoderedzwa, uye iyo yekushanda dura inogadzirwa neyakakodzera zirconium yakavakirwa yakasimba mhinduro zvinoenderana akasiyana magirazi mhinduro, ayo anogona kugadzirwa akasiyana zirconium akavakirwa yakasimba mhinduro zvigadzirwa zvemagirazi ane akasiyana zvinhu zvemukati, kuitira kuti uvandudze yakafara kushandiswa.
