Ziziphi izinto ezisetyenziswayo ekusebenzeni izitena ze-chrome ze-magnesia?

Izitena ze-Magnesia chrome ziyimveliso ephikisayo equkethe i-Cr2O3≥8% eyenziwe ngokongeza i-chromite kwi-sintered magnesia njengezinto eziluhlaza. Izigaba eziphambili zamaminerali ziyi-periclase kunye ne-chromium-containing spinel (MgO.Cr2O3).

Izitena ze-Magnesium chrome zinokuxhathisa okuthile kukhukuliseko lwe-alkaline ye-alkaline, ukuzinza kwevolumu elungileyo kumaqondo obushushu aphezulu, kunye nokushwabana okuncinci xa kutshiswe kwakhona kwi-1500 ° C. Ukungalungi okuphambili kukuba emva kokuba i-chromium spinel ithatha i-iron oxide, isakhiwo sesitena sitshintshwa, okubangela “ukunyuka kwamaxabiso” kunye nokukhawuleza umonakalo wezitena.

Izitena ze-Magnesium chrome zihlala zisetyenziselwa ukwakha iziko lokunyibilikisa ubhedu, izitofu zombane, ii-rotary kilns kunye neenxalenye ezithile zezitofu ezivulekileyo.
