Chromic corundum

Chrome corundum:
Kupangidwa kwakukulu kwa mchere ndi α-Al2O3-Cr2O3 yankho lolimba.
Kuphatikizika kwa mchere wachiwiri ndi kagawo kakang'ono ka spinel (kapena palibe pawiri spinel), ndipo zomwe zili mu chromium oxide ndi 1% ~ 30%.
Pali mitundu iwiri ya njerwa zosakanikirana za chrome corundum ndi njerwa za sintered chrome corundum.
Nthawi zambiri, njerwa ya chrome corundum imatanthawuza njerwa za sintered chrome corundum.Kugwiritsa ntchito α-Al2O3 ngati zopangira, kuwonjezera kuchuluka koyenera kwa chromic oxide ufa ndi chromic corundum clinker ufa, kupanga, kuyaka pa kutentha kwakukulu.Zomwe zili mu chromium oxide mu njerwa zolimba za sintered chrome nthawi zambiri zimakhala zotsika kuposa njerwa zosakanikirana za chrome corundum.Itha kukonzedwanso ndi njira yoponya matope.α-Al2O3 ufa ndi chromium oxide ufa zimasakanizidwa mofanana, ndipo degumming agent ndi organic binder amawonjezeredwa kuti apange matope wandiweyani.Panthawi imodzimodziyo, chromium corundum clinker imawonjezedwa, ndipo njerwa ya njerwa imapangidwa ndi njira ya grouting ndikuthamangitsidwa.Itha kugwiritsidwa ntchito ngati akalowa m'ng'anjo ya galasi, chivundikiro njerwa ya dzenje lotulutsa magalasi ndi kuchirikiza chipangizo chopangira zitsulo zotentha, chotenthetsera zinyalala, mpweya wa malasha, etc.
