Tsis ntev los no peb tau nug seb puas muaj siv lead ua ib qho cuam tshuam los ntawm anealing txheej txheem uas yog qhov tseem ceeb thiab zam tau, peb cov lus teb tsis muaj. Nov yog qee qhov laj thawj.
Annealing yog cov txheej txheem tseem ceeb hauv kev kho ntawm tib lub crystal tooj liab cov ntaub ntawv. Nws yog qhov tseem ceeb kom nkag siab tias annealing tsis muaj kev cuam tshuam rau qhov ntau ntawm ib lub lead ua tooj liab crystal. Thaum ib tug siv lead ua tooj liab tooj liab innegoes anegoes, lub hom phiaj tseem ceeb yog ua kom cov kev ntxhov siab thermal hauv cov khoom siv. Cov txheej txheem no tshwm sim yam tsis muaj kev hloov pauv ntawm cov muaju. Cov qauv siv lead ua tseem muaj zog, tsis nce ntxiv los yog tsis txo qis hauv qhov ntau.
Nyob rau hauv kev sib piv, cov txheej txheem ntawm kev kos duab muaj cov cawv tseem ceeb ntawm lub crystal morphology. Yog tias kos duab tau thov rau tib lub crystal tooj liab, luv luv thiab tuab thiab tuab thiab ua kom ntev. Piv txwv li, thaum muaj 8 hli pas nrig yog kos rau ib qho loj heev ntawm txoj kab ib nrab xws li ib feem ntawm ib qho muaju, cov muaju yuav ua tau kev sib tsoo. Nyob rau hauv ib qho xwm txheej heev, ib lub lead ua ib leeg tuaj yeem sib xyaw ua ob, peb, lossis ntau cov fragments nyob ntawm cov duab kos. Cov kev ntsuas no suav nrog kev kos duab nrawm thiab qhov sib piv ntawm cov duab kos. Txawm li cas los xij, txawm tias tom qab xws li tawg, lub ci ci muaju tseem tswj hwm cov duab continar thiab txuas ntxiv mus txuas ntxiv ntawm qee yam kev taw qhia.
Txhawm rau suav, annealing yog txheej txheem uas tsuas yog tsom rau kev ntxhov siab yam tsis tau hloov kho tus naj npawb ntawm ib lub crystal tooj liab crystal. Nws yog qhov kos duab uas tuaj yeem ua rau hloov cov crystal morphology thiab muaj peev xwm ua rau muaj cov ua lead ua fragmentation. Nkag siab cov kev sib txawv no yog qhov sib txawv yog qhov tseem ceeb rau kev ua kom zoo thiab siv cov ntaub ntawv crystal ib qho chaw muaj kev lag luam. Cov chaw tsim khoom thiab cov kws tshawb nrhiav yuav tsum saib xyuas cov qauv kev ua kom yog raws li cov kev xav tau ntawm cov khoom kawg. Seb nws yog los tswj kev ncaj ncees ntawm ib qho qauv siv lead ua thiab kev kos duab kom muaj kev nkag siab zoo ntawm kev ua tiav ntawm tib lub crystal tooj ua.
