Bauxite y'uruganda rw'Ubushinwa iragurishwa
Bauxite
Ibisobanuro birambuye:
Bauxite igizwe ahanini na alumina, ikaba ari alumina y’amazi irimo imyanda, kandi ni ubwoko bw’imyunyu ngugu y’ubutaka. Yera cyangwa umweru udasa n’umweru, umuhondo wijimye cyangwa umutuku woroshye bitewe n’ingano y’icyuma. Ubucucike 3.45g/cm3ifite ubukana bwa 1-3, idasobanutse neza, iracikagurika. Iragoye cyane gushonga. Ntishongera mu mazi, ishongera mu gisubizo cya aside sulfurike na hydroxide ya sodiyumu. Ikoreshwa cyane cyane mu gushonga aluminiyumu no gukora ibikoresho birwanya ubukana.
Akamaro k'ibicuruzwa:
Inganda zikora ibintu bidasanzwe:
Ubushyuhe burwanya umuriro kugeza kuri dogere 17800C, imiterere ihamye ya shimi n'imikorere myiza y'umubiri.
Fibre idashya:
Ifite ibyiza byo kuba ifite uburemere bworoshye, idashobora gushyuha cyane, idashobora gushyuha neza, idashobora gutwara ubushyuhe bwinshi, ifite ubushobozi buke bwo gushyuha no kudakoresha ikoranabuhanga rya mashini.
