Lub teeb grey hlau, nkig. Tus txheeb ze ntom ntom 7.20. melting point (1244 degree). Kub taw tes 1962 degree. Soluble nyob rau hauv dilute acid. Manganese reacts nrog dej hauv dej thiab tuaj yeem ua nrog halogens, sulfur, phosphorus, carbon thiab silicon. Muaj cov ntawv cubic thiab tetragonal, thiab muaj cov qauv siv lead ua nyuaj. Nyob rau hauv melting, manganese vapor thiab oxygen nyob rau hauv cov huab cua tsim oxides. Electrolytic manganese hlau feem ntau muaj ntau tshaj 99.7% manganese. Ntshiab electrolytic manganese tsis tuaj yeem ua tiav, tab sis yog tias 1% npib tsib xee ntxiv, nws dhau los ua cov hlau tsis zoo.
Hauv kev lag luam hlau thiab hlau, nws tsuas yog siv rau hauv desulfurization thiab deoxidation ntawm hlau; Nws kuj yog siv los ua cov khoom siv ntxiv los txhim kho lub zog, hardness, elasticity txwv, puas kuj thiab corrosion kuj ntawm steel, thiab lwm yam .; nws kuj yog siv los ua austenitic compounding element nyob rau hauv siab -alloyed steel thiab yog siv nyob rau hauv lub refining ntawm stainless hlau, tshwj xeeb alloy hlau thiab stainless hlau welding rods. Tsis tas li ntawd, nws kuj tseem siv rau hauv cov hlau tsis yog -ferrous hlau, tshuaj lom neeg kev lag luam, tshuaj, khoom noj khoom haus, kev soj ntsuam thiab kev tshawb fawb.
