Li-calcined alumina powders li entsoe ka calcination e tobileng ea indasteri ea alumina kapa aluminium hydroxide ka mocheso o nepahetseng ho fetoha crystallineα-alumina e tsitsitseng, ebe e sila ka phofo e nyenyane. Li-micro-powders tse calcined li ka sebelisoa hekeng ea li-slide, li-nozzles le litene tsa alumina. Ho phaella moo, li ka sebelisoa ka li-castable tse nang le mosi oa silica le li-powders tsa alumina tse sebetsang, ho fokotsa ho eketsa metsi, porosity le ho eketsa matla, botsitso ba molumo.
