Cov mis nyuj: CAC2, yog xim av xim av lossis cov khoom lag luam tsaus nti thiab nquag muaj impurities (piv txwv li phosphine, hydrogen sulfide).
Reactivity:
Nyob rau hauv kev sib cuag nrog dej, yam khoom undergoes kev tawm tsam sai thiab ua rau muaj kev tawm tsam, ua acetylene (c₂h₂) thiab calcium hydroxide. Qhov tshuaj tiv thaiv no yog li nquag uas tawg kev tiv thaiv yog qhov yuav tsum tau ua.
Cov tshuaj tiv thaiv nitrogen: tsim ntawm calcium cyanamide (CACNN2, cov chiv thiab tshuaj pub noj kom sov.
