Fahimtar kaddarorin sa na zahiri, kamar su narkewa aya da kuma tafasa, yana da mahimmanci don amintaccen mu'amala da amfani mai kyau a cikin hanyoyin masana'antu daban-daban. Don haka, menene ainihin ma'anar narkewa da wurin tafasa sodium cyanide?
Da narkewar batu na sodium Cyanide yana kusan 563.7 °C (1.046.7 °F). A wannan zafin jiki, m Sodium cyanide canzawa zuwa yanayin ruwa. Wurin tafasa na sodium cyanide yana kusa da 1.496 ° C (2.725 ° F). Lokacin da aka yi zafi zuwa wannan zafin jiki, ruwan sodium cyanide yana vaporize kuma ya juya zuwa yanayin gaseous.
Waɗannan ƙayyadaddun wuraren narkewa da wuraren tafasa su ne sakamakon ƙuƙƙarfan igiyoyin ionic a cikin lattice crystal cyanide. Sodium cyanide wani fili ne na ionic da aka samar ta hanyar halayen sodium ions (Na+) da cyanide ions (CN-).
