Izitena Ezirhabaxa Zodongwe
Izitena zodongwe lomlilozizinto ezichasene ne-silico-aluminous ezinomxholo we-Al₂O₃ ongama-35%–45%. Zenziwe ngokuyintloko nge-kaolin, zenziwe zayimilo, zomiswe, emva koko zitshiswa kubushushu obuphezulu be-1300–1400℃. Ngexesha lenkqubo yokudubula, kwenziwa iikristale ze-mullite. Ngokumelana ne-1690–1730℃, izitena zodongwe lomlilo zihlelwa njengeemveliso ezichasene ne-asidi encinci.
Ulwahlulo
Izitena zodongwe lomlilo zingahlulwahlulwa zibe ziintlobo ezine: eziqhelekileyo, ezixineneyo, eziphantsi kokurhubuluza, nezimelana nobushushu, zigubungela amanqanaba ahlukeneyo ngomxholo we-Al₂O₃ oqala kwi-25% ukuya kwi-45%. Ngokweemeko zokusetyenziswa, zahlulwe zibe ziintlobo ezintathu: ezo zezifutho zomlilo, izitovu zomlilo ezishushu, kunye nezifutho zeglasi.
Iimpawu eziphambili:
Izitena zodongwe ezisetyenziswa emlilweni zimelana kakuhle ne-asidi slag kunye ne-acid gas corrosion, kodwa azimelani kakuhle nezinto ze-alkaline. Zimelana kakuhle nobushushu: kubushushu obuphakathi kwe-0–1000℃, umthamo wazo uyanda ngokulinganayo ngobushushu obukhulayo, ngesantya sokwanda esithe ngqo se-0.6%–0.7%, esimalunga nesiqingatha sezitena ze-silica. Nangona kunjalo, ukunganyamezeli kwazo phantsi komthwalo kungaphantsi kwama-200℃ kunokwezitena ze-silica, kwaye ukuncitshiswa komthamo kwenzeka xa ubushushu budlula i-1200℃.
