Kariya ga alumina crucible

Ana iya amfani da Corundum crucible don narkewa da ɓarke ​​​​na wasu kwararar alkaline, amma zafin jiki bai kamata ya yi girma ba, kuma lokacin ya kamata ya zama gajere gwargwadon yiwu. A wasu lokuta, yana iya maye gurbin nickel da platinum crucibles, amma ma’auni na aluminum da aluminum yana tsoma baki tare da ma’auni. Ba za a iya amfani da karkashin.

Menene bambanci tsakanin ƙananan zafin jiki na alumina da babban zafin jiki alumina

Dukansu alumina masu ƙarancin zafin jiki da alumina masu zafin jiki na alumina ne, kuma akwai nau’ikan lu’ulu’u da yawa. Canjin zafin jiki na iya gane canji a tsakanin abubuwa, kuma ƙananan zafin jiki na alumina za a iya canza shi zuwa α-crystal alumina bayan ƙididdigar zafin jiki mai zafi.

Babban zafin jiki na alumina shine farin foda, wanda alumina ya daidaita shi. A hakikanin gaskiya, ana amfani da alumina masu zafi mafi yawa, kuma ana iya ƙara kayan ƙananan zafin jiki tare da wasu abubuwa masu alama.
