Tam sim no, muaj ob txoj kev npaj tseem ceeb rau kev lag luam hlau calcium hauv tsev thiab txawv teb chaws: electrolysis thiab thermal txo. Lub hom phiaj yog nyob rau hauv cov txheej txheem, cov cuab yeej siv thiab kev nce qib ntawm lub tshuab nqus tsev distillation rau kev npaj high-purity metallic calcium. Electrolysis thiab thermal txo yog cov tshuaj purification txoj kev uas nyuaj rau Npaj siab purity hlau calcium. Siv cov khoom siv calcium ua raw khoom, lub tshuab nqus tsev distillation tuaj yeem siv los npaj cov purity hlau calcium uas muaj purity ntau dua 99.999% (5N).
Raws li kev tshawb fawb yav dhau los, qhov ntsuas kub condensing tau txheeb xyuas ntxiv thiab suav qhov theoretical, thiab cov khoom siv hlau calcium nqus distillation purification khoom tsim nyog rau kev tsim khoom tsim thiab tsim los ntawm nws tus kheej. Kev sim tshawb fawb ntawm cov khoom siv sib txawv tau pom tias cov phab ntsa sab hauv ntawm 304 series stainless hlau tank Tom qab chromium plating, nws tuaj yeem txo cov nyhuv ntawm cov khoom siv rau kev ua kom huv ntawm cov hlau calcium. Ua ke nrog cov txiaj ntsig ntawm kev tshawb fawb yav dhau los, tom qab ib-kauj ruam kev sim distillation, purity yog siab li 99.99%, cov ntsiab lus calcium nquag yog siab li 99.5%, thiab cov ntsiab lus roj tsawg (C
