Cesium Chloride (CsCl)

Kayayyakin Asali
Cesium chloride (CsCl) wani sinadari ne na ƙarfe na alkali wanda ke da sinadarin CsCl kuma nauyin ƙwayoyin halitta ya kai 168.36 g/mol. Lu'ulu'u ne mai siffar cubic wanda ba shi da launi tare da wurin narkewa na 645°C, wurin tafasa na 1297°C, da kuma yawan 3.988 g/cm³ (25°C). CsCl yana da yawan narkewa a cikin ruwa (1910 g/L, 20°C), kuma narkewarsa yana canzawa sosai tare da zafin jiki (~2500 g/L, 100°C). Sau da yawa ana amfani da wannan sinadari wajen tsarkake cesium. Tsarin lu'ulu'unsa mai siffar cubic ne mai sauƙi (ƙungiyar sararin samaniya ta Pm-3m) a zafin ɗaki. Kowane Cs⁺ yana da daidaituwa ta hanyar 8 Cl⁻. Ba kamar tsarin nau'in NaCl ba, wannan tsari na musamman ya sa ya zama abu na yau da kullun don nazarin samfuran lu'ulu'u na ionic.

    Hanyar shiri

    Shirye-shiryen masana'antu galibi yana faruwa ne ta hanyoyi masu zuwa:
    1. Amsar cesium na ƙarfe tare da hydrochloric acid
    2. Hanyar raba sinadarin sinadarai da cesium carbonate ko cesium hydroxide:
    3. Hako ma'adinai: Ana samun CsCl mai tsarki sosai daga pollucite ta hanyar cire sinadarin acid, musayar ion da sauran matakai.

    Sinadaran sinadarai da na jiki

    Maganin yawan amfani: Yawan ruwan CsCl mai cikewa zai iya kaiwa 1.9 g/cm³, wanda galibi ana amfani da shi don raba samfuran halittu masu yawa (kamar tsarkakewar DNA).
    Madaidaita wutar lantarki ta ionic: Molten CsCl kyakkyawan mai sarrafa ion ne kuma ana amfani da shi don binciken electrolyte mai zafi sosai.
    Kayayyakin gani: Gilashin CsCl suna da kewayon watsa haske mai faɗi (0.2 ~ 55 μm) kuma ana iya amfani da su don prisms na infrared spectrometer.
    Aikace-aikacen rediyoaktif: Ana amfani da tushen hasken gamma na Cs-137** (rabin rai shekaru 30.17) sosai a fannin likitanci da kuma hasken masana'antu.

    1. Ilimin halittar kwayoyin halitta:
    Ana amfani da centrifugation mai yawa don raba ƙwayoyin nucleic da ƙwayoyin cuta.
    A matsayin wani sinadari mai hana ruwa ga halayen PCR.
    2. Maganin nukiliya:
    Ana amfani da Cs-131 (rabin rai na kwanaki 9.7) don maganin brachytherapy na ciwon daji na prostate.
    3. Kimiyyar kayan aiki:
    Shirye-shiryen tururin cesium don bututun photoelectric da ion thrusters.
    Haɗa kayan aiki masu aiki tare da tsarin CsCl (kamar su masu haɓaka ƙwayoyin hasken rana na perovskite).

    Bincike na asali

    Ana amfani da shi don shirya lattices na gani a cikin gwaje-gwajen atom mai sanyi sosai.
    Yi nazarin yanayin sauyawar lokaci na lu'ulu'u na ionic (wanda aka canza zuwa tsarin nau'in NaCl a babban zafin jiki).

    Tsaro da ajiya

    CsCl yana da ɗan guba kaɗan (ba a sha beraye LD₅₀ ta baki yana da kusan 2300 mg/kg), amma ana buƙatar a kare isotopes masu rediyoaktif sosai. Ajiya yana buƙatar a rufe shi da danshi don guje wa hulɗa da sinadarai masu ƙarfi. Ana buƙatar a sarrafa kayan rediyoaktif kamar Cs-137 bisa ga ƙa'idodin tsaron nukiliya.

    Kammalawa

    Saboda tsarin kristal na musamman, kyawun narkewar sa da kuma nau'ikan halayen isotopic daban-daban, cesium chloride yana da matsayi mai mahimmanci a fannonin kimiyyar rayuwa, fasahar nukiliya da kayan aiki. Aikace-aikacensa sun shafi daga bincike na asali zuwa fasaha mai zurfi, yana nuna ƙimar aiki da yawa na halides na ƙarfe alkali.
