Sodium cyanide (NaCN) wani sinadari ne mai guba wanda ke da amfani mai yawa a masana'antu , amma kuma yana haifar da haɗari mai tsanani saboda gubarsa. Fahimtar halayensa na zahiri, kamar wurin narkewa da wurin tafasa , yana da mahimmanci don amfani da shi cikin aminci da kuma amfani da shi yadda ya kamata a cikin ayyukan masana'antu daban-daban. To, menene ainihin wurin narkewa da wurin tafasa na sodium cyanide?
Wurin narkewar Sodium Cyanide yana da kimanin 563.7 °C (1.046.7 °F). A wannan zafin, Sodium cyanide mai ƙarfi yana canzawa zuwa yanayin ruwa. Wurin tafasar Sodium cyanide yana kusa da 1.496 °C (2.725 °F). Idan aka dumama shi zuwa wannan zafin, ruwan sodium cyanide yana tururi kuma yana juyawa zuwa yanayin iskar gas.
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-). Abubuwan jan hankali na electrostatic tsakanin ions sodium da aka caje da kyau da kuma ions cyanide da aka caje mara kyau suna haifar da tsayayyen tsari wanda ke buƙatar adadin kuzari mai yawa don karya, yana haifar da babban narkewa da wuraren tafasa.
Ganin yawan narkewar ta da wuraren tafasa, sodium cyanide ya kasance barga a ƙarƙashin yanayin yanayi na yau da kullun. Sai dai kuma idan aka gamu da matsanancin zafi musamman kusa ko sama da wurin tafasarsa, tana iya sakin iskar iskar hydrogen cyanide mai guba mai tsananin gaske, wanda ke da matukar hadari ga lafiyar dan Adam da muhalli.
A cikin saitunan masana'antu, inda ake amfani da sodium cyanide a cikin matakai kamar hakar zinari da azurfa, electroplating, da haɗin sinadarai, tsauraran ka'idojin aminci suna cikin wuri don hana bayyanar haɗari da sakin abubuwa masu guba. Ma'aikatan da ke sarrafa sodium cyanide dole ne su kasance masu horarwa da kyau kuma suna sanye da kayan kariya masu dacewa.
A ƙarshe, wurin narkewar sodium cyanide yana kusan 563.7 ° C, kuma wurin tafasa yana kusa da 1.496 ° C. Waɗannan kaddarorin na zahiri suna da mahimmanci don sanin duk wanda ke aiki tare da ko nazarin wannan fili don tabbatar da aminci da ingantaccen amfani.
