Cov xim hlau oxide yog ib hom xim tseem ceeb ntawm cov xim inorganic nrog cov khoom xyaw tseem ceeb yog hlau oxides. Lawv yog cov xim inorganic thib ob loj tshaj plaws tom qab titanium dioxide thiab cov xim inorganic tseem ceeb tshaj plaws, pom kev siv dav hauv kev lag luam thiab kev siv txhua hnub.
Hauv kev siv tshuaj lom neeg, lawv feem ntau muaj plaub pawg: hlau oxide liab, hlau oxide daj, hlau oxide dub, thiab hlau oxide xim av. Ntawm lawv, hlau oxide liab yog qhov feem ntau, suav txog li 50% ntawm tag nrho cov xim hlau oxide. Tsis tas li ntawd, micaceous hlau oxide, siv ua xim tiv thaiv xeb, thiab hlau oxide sib nqus, rau cov ntaub ntawv sau sib nqus, kuj poob rau hauv qhov ntau ntawm cov xim hlau oxide. Ntau hom xim hlau oxide muaj ntau yam xim vim muaj ntau yam xeev oxidation ntawm hlau. Piv txwv li, hlau oxide liab, muab los ntawm ferric oxide (Fe₂O₃), zoo li liab; hlau oxide daj, los ntawm hydrated ferric oxide (Fe₂O₃·H₂O), yog daj; thiab hlau oxide dub, uas yog magnetite (Fe₃O₄), qhia dub.
Hais txog kev ua tau zoo, cov xim hlau oxide zoo kawg nkaus. Lawv cov kua qaub thiab alkali tsis kam zoo heev. Lawv ruaj khov heev rau ntau yam alkalis thiab cov khoom siv hauv tsev xws li cement thiab lime mortar, yam tsis ua rau cov khoom siv hauv tsev cement puas tsuaj lossis cuam tshuam rau lawv lub zog. Txawm li cas los xij, lawv maj mam yaj hauv cov kua qaub muaj zog, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias. Hais txog kev tiv thaiv lub teeb thiab cua sov, cov xim hlau oxide ib txwm ruaj khov hauv qee qhov kub thiab txias. Piv txwv li, hlau oxide daj hloov liab - hued thaum tshaj 130 ° C, thiab hlau oxide liab tob zuj zus mus rau liab tsaus saum 300 ° C. Txawm li cas los xij, ntau lub tuam txhab tam sim no tau tsim cov khoom lag luam nrog kev ua tau zoo dua uas tuaj yeem tiv taus qhov kub siab dua. Lawv cov huab cua tsis kam zoo heev, tsis muaj kev cuam tshuam los ntawm cov huab cua xws li txias, kub, qhuav, thiab av noo hauv huab cua, ua rau lawv pom tseeb hauv kev siv sab nraum zoov. Ntxiv mus, lawv ruaj khov hauv cov pa phem, tsis yaj hauv dej, roj av, roj zaub, thiab ntau cov kuab tshuaj organic, thiab tsis qhia kev nkag mus.
