Phosphorus Hlau

 

atomic tooj ntawm phosphorus yog 15, atomic hnyav yog 30.97, sab nraud hluav taws xob qauv yog 3S3P, qhov ceev yog 1.83g / cm3 (dawb phosphorus) thiab 2.2g / cm3 (liab phosphorus), lub melting point yog 44 degree, thiab Qhov kub ntawm qhov kub yog 257 degrees. Phosphides muaj xws li Fe3P, Fe2P, FeP, FeP2, thiab lwm yam. Phosphorus hlau muaj 18% mus rau 25% phosphorus muaj ib tug melting kub ntawm 1100 ~ 1250 degree thiab ib tug ceev ntawm 5.8 ~ 6.5g / cm3.

Ferrophosphorusyog ib tug compound ntawm phosphorus thiab hlau. Nws cov qauv molecular tuaj yeem sau ua FenPm, qhov twg n yog 1, 2 lossis 3; m yog 1 lossis 2. Lub ntsiab hlau phosphides yog Fe3P, Fe2P, FeP thiab FeP2. Cov khoom siv hlau phosphide tau los ntawm kev tsim khoom lag luam feem ntau yog tsim los ntawm cov hlau phosphide saum toj no. Feem ntau, ferrophosphorus muaj li ntawm 70% hlau, li 20% mus rau 26% phosphorus, thiab ib qho me me ntawm manganese, titanium, silicon, vanadium, calcium thiab lwm yam khoom.

 

Cov khoom siv Ferrophosphorus yog siv rau hauv smelting ntawm cov hlau tshwj xeeb hauv kev lag luam metallurgical los txhim kho cov hnav tsis kam thiab corrosion tsis kam ntawm cov hlau, thiab tuaj yeem txhim kho cov khoom ntawm ferroalloys; Hauv kev lag luam tshuaj, ferrophosphorus tuaj yeem kho nrog dej qab zib tshauv los tsim sodium dihydrogen phosphate thiab triphosphate. Sodium, thiab tuaj yeem ua tiav rau hauv sodium tripolyphosphate, sodium hexametaphosphate thiab lwm yam khoom.
