Cov ntsiab lus ntxiv rau cov hlau txiav dawb muaj xws li S, Pb, Ca thiab P. Lawv lub luag haujlwm tseem ceeb yog raws li nram no:
1. Lub luag haujlwm ntawm cov leej faj
Cov sulfur tsim cov MnS uas muaj Mn hauv cov hlau, uas tuaj yeem cuam tshuam kev sib txuas ntawm lub matrix, ua rau cov chips yooj yim tawg, thiab txo qhov chaw sib cuag ntawm cov chips thiab cov cuab yeej. Sulfur kuj tseem tuaj yeem txo qhov kev sib txhuam thiab tiv thaiv cov chips kom tsis txhob lo rau ntawm ntug txiav. Txawm li cas los xij, qhov muaj sulfur tuaj yeem ua rau hlau kub thiab tawg, yog li cov sulfur feem ntau tsuas yog txwv rau qhov ntau ntawm w(s)=0.10%~0.30%, thiab cov ntsiab lus Mn yuav tsum tau nce kom haum rau nws.
2. Lub luag haujlwm ntawm cov hlau lead
Qhov ntxiv Pb tuaj yeem txhim kho kev ua tau zoo ntawm kev txiav hlau. Vim tias Pb tsis yaj mus rau hauv ferrite hauv hlau thiab tsis tsim cov tshuaj sib xyaw, nws nyob hauv lub xeev dawb thiab tsim cov khoom me me (2 ~ 3μm) faib sib npaug hauv cov qauv matrix. Thaum lub cua sov tsim thaum lub sijhawm txiav mus txog qhov chaw yaj ntawm cov khoom Pb, nws nyob hauv lub xeev yaj thiab dhau los ua "lubricant" ntawm cov cuab yeej thiab cov chips thiab ntawm cov cuab yeej thiab qhov chaw ua haujlwm, txo cov yam ntxwv sib txhuam, qhov kub ntawm cov cuab yeej, thiab kev hnav. Tus nqi ntawm Pb ntxiv yog nyob rau hauv qhov ntau ntawm w (Pb) = 0.1% ~ 0.35%.
3. Lub luag haujlwm ntawm calcium
Ca tuaj yeem tsim cov Ca thiab Al silicate inclusions hauv cov hlau, uas lo rau cov cuab yeej los ua ib daim nyias nyias, muaj cov nyhuv txo kev sib txhuam, thiab tiv thaiv cov cuab yeej hnav. Qhov ntau ntawm Ca ntxiv yog w (Ca) = 0.001% ~ 0.005%.
4. Lub luag haujlwm ntawm phosphorus
P ntxiv rau hauv cov hlau txiav dawb uas muaj sulfur kom yaj nws hauv ferrite, ua rau muaj zog thiab tawg kom txhim kho nws txoj kev txiav. Txhawm rau tiv thaiv "txias brittleness", w (P) tau teev tseg kom yog ≤0.15%.
Qhov ntxiv cov ntsiab lus no kuj tseem tuaj yeem txhim kho qhov zoo ntawm qhov chaw ua haujlwm thiab txuas ntxiv lub neej ua haujlwm ntawm lub cuab yeej.
