Calcium chloride (cov tshuaj formula: CaCl2) yog dawb los yog daj me ntsis cov khoom inorganic compound, teej tug mus rau cov chav kawm ntsev, yog ib tug raug ionic halide, vim hais tias ntawm nws cov solubility siab, hygroscopicity thiab lub cev qhuav dej zog yog dav siv nyob rau hauv ntau lub teb. Nws muaj nyob rau hauv cov ntaub ntawv sib txawv ntawm lub cev raws li nws daim ntawv hydrated, feem ntau yog dihydrate (CaCl2 · 2H2O), uas nws cov solubility siab tso cai rau nws yaj sai sai hauv dej, tso tawm ntau cov cua sov, ua rau nws siv tau rau hauv daim ntawv thov uas yuav tsum tau ceev ceev. cua sov los yog ziab. Tsis tas li ntawd, calcium chloride kuj tau siv dav hauv brine, txoj kev ice melting agents thiab desiccant, nrog rau cov khoom siv hauv tub yees.
