Potassium Chloride | 7447-40-7 ib
Khoom Description
Cov tshuaj sib xyaw potassium chloride (KCl) yog hlau halide ntsev uas muaj cov poov tshuaj thiab chlorine. Hauv nws lub xeev ntshiab, nws tsis muaj ntxhiab thiab muaj xim dawb lossis tsis muaj xim vitreous siv lead ua, nrog cov qauv siv lead ua uas cleaves yooj yim hauv peb cov lus qhia. Potassium chloride crystals yog lub ntsej muag-centered cubic. Potassium chloride yog keeb kwm hu ua "muriate ntawm potash". Lub npe no yog qee zaum tseem ntsib nrog kev koom tes nrog nws siv ua chiv. Potash sib txawv nyob rau hauv cov xim ntawm liab los yog liab mus rau dawb nyob ntawm seb lub mining thiab rov qab txheej txheem siv. Dawb potash, qee zaum hu ua soluble potash, feem ntau yog siab dua hauv kev tshuaj xyuas thiab siv feem ntau los ua kua chiv chiv. KCl yog siv rau hauv cov tshuaj, kev siv scientific, thiab kev ua zaub mov. Nws tshwm sim raws li cov ntxhia sylvite thiab ua ke nrog sodium chloride li sylvinite.
