Lub teeb Thiab Hnyav Basic Cmgo3 Magnesium Carbonate Nrog Cas 13717-00-5
Magnesium carbonate yog cov hmoov dawb tsis muaj ntxhiab, uas muaj ob hom: amorphous hmoov thiab monoclinic siv lead ua.Nws yog tus cwj pwm los ntawm kev tsis sib haum xeeb thiab kev ntxhib los mos yooj yim, thiab tuaj yeem siv los ua cov khoom siv hluav taws xob hluav taws xob rau cov rwb thaiv tsev kub thiab kub ua haujlwm.
