piav qhia ntawm ferro phosphorus
Ferrophosphorusyog ib qho alloy ntawm hlau thiab phosphorus. Cov ferroalloy no muaj cov feem ntau ntawm Hlau Phosphides, Fe₂P, thiab Fe₃P.
Raws li ib qho tseem ceeb inorganic khoom, ferrophosphorus muaj lub cev zoo thiab tshuaj lom neeg thiab siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, kev ua liaj ua teb, thiab lwm yam. Txawm li cas los xij, thaum siv hlau phosphorus, nws yog ib qho tsim nyog yuav tsum tau xyuam xim rau nws cov kev cuam tshuam rau ib puag ncig thiab tib neeg lub cev kom ntseeg tau tias kev siv nyab xeeb.
Cov yam ntxwv ntawm ferrophosphorus
atomic tooj ntawm phosphorus yog 15, atomic hnyav yog 30.97, cov txheej txheem hluav taws xob 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. Muaj phosphides xws li Fe3P, Fe2P, FeP, thiab FeP2. Lub melting kub ntau yam ntawm hlau muaj 18% mus rau 25% phosphorus yog 1100 ~ 1250 degree, thiab qhov ceev yog 5.8 ~ 6.5g / cm3.

Kev siv ferrophosphorus
Ferrophosphorus reacted nrog sulfur los yog pyrite, yog siv rau zus tau tej cov phosphorus pentasulfide.
Ferrophosphorus tuaj yeem muab ntxiv rau cam khwb cia hlau, qhov twg phosphorus txhim kho fluidity thiab yog li zoo ntawm cov castings, uas yuav ua rau kom hnav tsis kam thiab cutability. Hauv cov hlau, nws ntxiv rau qee cov alloys tuaj yeem txhim kho corrosion kuj.
Kev tsim cov ferrophosphorus
Ferrophosphorus yog tsim los ntawm kev txo apatite nrog carbon ntawm qhov kub thiab txias. Silica yog ntxiv rau daim ntawv calcium silicate. Ntxiv cov hlau scraps thiab rov qab kho qhov qub apatite. Silica yog ntxiv rau daim ntawv calcium silicate. Ntxiv steel scraps thiab txo phosphorus los tsim Fe2P.
