Pakali pano, pali njira ziwiri zazikulu zokonzekera mafakitale zitsulo kashiamu kunyumba ndi kunja: electrolysis ndi kuchepetsa matenthedwe. Cholinga chake ndi njira, zida ndi kupita patsogolo kwa vacuum distillation pokonzekera zitsulo zoyera kwambiri za calcium. Electrolysis ndi kuchepetsa kutentha ndi njira zoyeretsera mankhwala zomwe zimakhala zovuta Kukonzekera kashiamu woyeretsedwa kwambiri wachitsulo. Pogwiritsa ntchito kashiamu wa mafakitale monga zopangira, kutsekemera kwa vacuum kungagwiritsidwe ntchito pokonzekera calcium yoyera yachitsulo yokhala ndi chiyero choposa 99.999% (5N).
Pamaziko a kafukufuku wam'mbuyomu, kutentha kwa condensing kudawunikidwanso ndikuwerengeredwa mongoyerekeza, ndipo chipangizo choyeretsera chachitsulo cha calcium vacuum distillation choyenera kupanga mafakitale chidapangidwa ndikupangidwa chokha. Kafukufuku woyeserera pazida zosiyanasiyana zidawonetsa kuti khoma lamkati la thanki yazitsulo zosapanga dzimbiri la 304 Pambuyo pakupanga chromium, limatha kuchepetsa mphamvu ya zida zachitsulo pakuyeretsa kashiamu. Kuphatikizidwa ndi zotsatira za kafukufuku wam'mbuyomu, pambuyo pa kuyesa kwa gawo limodzi la distillation, chiyero chimakhala chokwera mpaka 99.99%, calcium yogwira ntchito imakhala yokwera mpaka 99.5%, ndipo mpweya wake ndi wotsika (C).
