Ferric oxide, tshuaj formula Fe₂O₃. Kuj tseem hu ua hlawv limonite, hlawv ocher, hlau liab, hlau liab, hmoov liab, Venice liab (cov khoom tseem ceeb yog hlau oxide), thiab lwm yam, nws yooj yim soluble hauv cov kua qaub, nruab nrab muaj zog acid, thiab nws cov tsos yog xim daj hmoov Nws cov xim av xim av xim av yog cov xim qis, tsim los hu ua hlau oxide liab, siv xim, xim number case, roj hmab thiab lwm yam lag luam, raws li cov tshuaj tiv thaiv, tus neeg sawv cev polishing rau iav, lub pov haum, thiab hlau, thiab ua raw khoom rau hlau .
Hlau oxide yog lub hauv paus tseem ceeb ntawm xeb. Lub hauv paus tseem ceeb ntawm xeb yog tias cov hlau hlau cuam tshuam nrog cov dej noo thiab cov pa oxygen hauv ib puag ncig thaum muaj cov pa tsis huv, thiab cov hlau hlau yuav xeb. Siv hauv cov xim, number case, roj hmab thiab lwm yam lag luam, nws tuaj yeem siv ua cov tshuaj tiv thaiv, tus neeg sawv cev polishing rau iav, lub pov haum, thiab hlau, thiab tuaj yeem siv ua raw khoom rau kev ua hlau. Daim ntawv thov loj tshaj ntawm cov hlau oxide yog ua cov xim. Raws li cov xim, nws tau muab faib ua hlau oxide liab, hlau oxide daj, thiab hlau oxide dub. Hlau oxide xim av yog sib xyaw ntawm hlau oxide liab thiab hlau oxide dub (thiab hlau oxide daj); hlau oxide txiv kab ntxwv yog sib xyaw ntawm hlau oxide liab thiab hlau oxide daj Cov hlau oxide ntsuab yog sib xyaw ntawm xiav phthalocyanine xiav thiab hlau oxide daj.
Kev ruaj ntseg: ruaj khov, soluble hauv hydrochloric acid thiab dilute sulfuric acid los ua hlau ntsev. Cov hlau hlau tsim cov hlau ions hauv cov tshuaj tiv thaiv kev hloov pauv.
Kev ntim khoom thiab thauj mus los: Khaws rau hauv qhov chaw qhuav, tsis txhob ya raws, zam qhov kub thiab cais nws los ntawm cov kua qaub thiab alkalis. Raws li cov xwm txheej khaws cia saum toj no, lub sijhawm khaws cia tau zoo ntawm cov khoom tsis tau qhib yog peb xyoos. Solubility: tsis yooj yim yaj hauv dej thiab tsis cuam tshuam nrog dej. Nws yog soluble hauv acid thiab reacts nrog acid. Tsis hnov mob nrog sodium hydroxide. Hlau oxide reacts nrog acid los ua hlau ntsev thiab dej. Piv txwv: Thermite cov tshuaj tiv thaiv Aluminium thiab hlau oxide tau sib xyaw los ua tus neeg sawv cev thermite, uas tau muab rhaub kom tsim alumina thiab hlau.
Cov pa roj carbon thiab cov pa roj carbon monoxide txo cov hlau oxide tuaj yeem sib xyaw nrog cov pa roj carbon thiab ua kom sov kom tshem tawm cov hlau thiab carbon dioxide.
