Umushinga wo hejuru wo gusya Alumina
Gusaba
Gusya imipira ikoreshwa cyane mubikorwa bitandukanye byo gukora mu nganda nka ceramika, emamel, ibirahure, n’ibiti bivura imiti.By'umwihariko muburyo bwo gusya, kuva neza kugeza gutunganya byimbitse ndetse binini cyane kandi bikomeye.Bitewe nuburyo bwo gusya no kwambara (ugereranije namabuye asanzwe yumupira cyangwa ubundi buryo bwa kaburimbo busanzwe), imipira ya ceramic ya alumina ikoreshwa nkibikoresho byo gusya bikoreshwa mu gusya imipira, urusyo, inkono zinyeganyeza nibindi bikoresho byinshi byo gusya.
