Vim tias cov txheej txheem tshwj xeeb ntawm cov khoom siv tsis zoo, kev ua haujlwm zoo hydrophilic, nws cov nplaim tuaj yeem tsim cov zaj duab xis ua kua nyias ntawm cov cua ntsawj ntshab qaij thiab cov kuab paug tuaj yeem txhawb nqa huab cua tab sis tsis tso tseg cov hlau muab cov cua tuaj yeem ua rau cov pob zeb ntim khoom, thiab nws cov xeb tiv taus, siab qhov ua haujlwm tiv taus kub ntawm cov muab tub lim hlau tsis tuaj yeem sib piv. Cov txheej txheem saum npoo muaj cov khoom ntub zoo, tuaj yeem ua kom cov kua ntws tawm, ua rau ntim cov dej ntim qis kom tsawg kawg. Txhawm rau txo txoj hauv kev ua kom sov, sib sau ua ke, thiab haus luam yeeb. Cov khoom no yog ua los ntawm cov khoom lag luam zoo cov plooj (porcelain) av nplaum ua cov txheej txheem thiab dhau los, tiv taus qhov kub thiab txias siab, tshuaj zoo ruaj khov thiab muaj zog siab, yog cov khoom siv zoo tshaj plaws los txhawb nqa ntau hom catalysts.
