Cov mis mos molecular ntawm hlau oxide liab yog Fe2O3, lub ntsiab tivthaiv yog ferric oxide, nws yog ib tug liab hmoov, muaj ob hom ntawm ntuj thiab dag, lub ntuj hu ua Xihong, uas yog yeej ib txwm ntshiab hlau oxide, nrog ib tug fineness ntawm. 0.4-20um thiab melting point ntawm 1565 (Decomposition), emit oxygen thaum hlawv, thiab yuav txo tau hlau los ntawm hydrogen thiab -carbon oxide; tib neeg tsim yog hluavtaws hlau oxide liab, theem ceev yog 5-5.25, nws cov qauv siv lead ua thiab lub cev muaj zog sib txawv, xim hloov Los ntawm lub teeb txiv kab ntxwv mus rau lub teeb xiav rau lub teeb liab doog, nws muaj lub zog npog zoo thiab lub zog tinting, zoo heev. Lub teeb tsis kam, kub tsis kam, thiab tsis kam rau atmospheric cawv, foul gas, thiab tag nrho cov alkalis, tsuas yog thaum rhuab nyob rau hauv concentrated acid. yuav maj mam yaj.
Muaj ob hom hlau oxide liab, ntuj thiab hluavtaws. Lub ntuj hu ua Xihong, nrog tus txheeb ze ntom ntom ntawm 55.25. Qhov zoo yog 0.4-20um. Melting point 1565 (decomposition). Oxygen raug tso tawm thaum hlawv, uas tuaj yeem txo cov hlau los ntawm hydrogen thiab carbon oxide. Insoluble hauv dej, soluble hauv hydrochloric acid, sulfuric acid, me ntsis soluble hauv nitric acid thiab poov xab. Nws muaj lub teeb pom kev zoo, kub tsis kam, acid tsis kam, alkali tsis kam thiab xeb kuj. Zoo dispersibility, muaj zog tinting zog thiab npog lub zog, tsis muaj roj permeability thiab dej permeability. Tsis muaj tshuaj lom. Qhov siab tso cai nyob rau hauv huab cua yog 5mg / m3.
