Calcined Alumina Ultrafine For High-Performance Refractories, za a iya amfani da castables tare da silica fume da reactive alumina powders, don rage ruwa Bugu da kari, porosity da kuma ƙara ƙarfi, girma kwanciyar hankali.

Ceramic grade- Calcined Alumina

Alumina kayayyakin tare da irin calcined alumina foda a matsayin albarkatun kasa da kyau kwarai inji ƙarfi, high taurin, high lantarki resistivity da kuma mai kyau thermal watsin. A calcined alumina micropowder za a iya amfani da ko'ina a cikin lantarki kayan aiki, tsarin tukwane, refractories, abrasives, polishing kayan, da dai sauransu

Calcined aluminas su ne alpha-aluminas waɗanda suka ƙunshi da farko na sintered agglomerates na kowane lu'ulu'u na alumina. Girman waɗannan lu'ulu'u na farko ya dogara da matakin ƙididdiga da girman agglomerate akan matakan niƙa na gaba. Yawancin aluminas da aka yi amfani da su ana kawo su ƙasa (<63μm) ko ƙasa mai kyau (<45μm). The agglomerates ba su da cikakken karya a lokacin nika, wanda shi ne wani gagarumin bambanci daga reactive aluminas da aka cikakken ƙasa ta tsari nika tsari. Calcined aluminas an rarraba su ta hanyar abun ciki na soda, girman barbashi da digiri na calcination. Ana amfani da alumina mai ƙasƙan ƙasa da ƙasa mai kyau azaman matrix filler don haɓaka aikin samfur na ƙira galibi dangane da albarkatun ƙasa.
