[Umubiri na shimi]] Ifeza yumuhondo yera icyuma. Ubucucike bugereranije 3.62, Gushonga Ingingo 725 ℃, Ingingo yo Guteka 1640 ℃. Umubiri ushingiye ku cubi: α = 0.5025nm. Gushonga Ubushyuhe 7.66kJ / Mol, Ubushyuhe Bweshya 149.20kj / Mol, Kurwanya 61.3Kpa (16012 Ba2 + ifite radiyo ya 0.143nm hamwe nu muco wubushyuhe bwa 18.4 (25 ℃) w / (M · k). Gukwirakwiza umurongo hamwe 1.85 × 10-5 m / (m · ℃). Ku bushyuhe bwicyumba, byoroshye kubyitwaramo byoroshye amazi kugirango urekure gaze ya hydrognan, ikundwa gato muri alcool kandi idahujwe na benzene.
Ibipimo byiza]Ibipimo ngenderwaho
Porogaramu 【Byakoreshejwe cyane cyane mu bihindura, harimo kuyobora, Calcium, Magnesium, Sodium, Limininum, na Nikel Alloys. Ikoreshwa nka gaze yo gukuraho imyuka isigara muri wireless tubes, kandi ikoresha mugukora umunyu wa barium.
Uburyo bwo kugabanya ubushyuhe bwa Aluminium: nitrate ya barium yangirika kwabora kugirango umusaruro wa barium. Aluminum nziza yinzitizi ikoreshwa nkumukozi ugabanya, kandi igipimo cyibikoresho ni 3bao: 2a1. Barium oxide na aluminium bakorewe muri pellets, hanyuma bagashyirwa muri aagishya kandi bashyushye kugeza 1150 ℃ kugirango bagabanye isura yo kugabanuka. Ubuziranenge bwa bariyi yavuyemo ni 99%.
Umutekano】Umukungugu ugaragara ko uzirikana hejuru yubushyuhe bwicyumba kandi birashobora gutera gutwikwa no guturika mugihe uhuye nubushyuhe, umuriro, cyangwa imiti. Bikunda kubora amazi kandi bikatirwa bikabije hamwe na acide, kurekura gaze ya hydrogrog ishobora guteshwa agaciro nubushyuhe bwimyitwarire. Guhura na fluorine, chlorine, nibindi bintu birashobora gutera imiti. Bariimic yitabira amazi kugirango ice hydroxide, ifite ingaruka mbi. Mugihe kimwe, umunyu wa sahone wamazi ni uburozi cyane. Iyi ngingo irashobora kwangiza ibidukikije, birasabwa kutareka ngo ifate ibidukikije.
Kode ya Hazard: ikintu cyaka guhura nubushuhe. GB 4.3 Icyiciro cya 43009. UN No. 800. IMDG Code 4332 page, icyiciro 4.3.
Iyo uyifata nabi, unywe amazi menshi, kuruka, oza igifu hamwe na 2% kuri 5% ya sodium suldium, kandi ushake ubwikunde. Guhumeka umukungugu birashobora gutera uburozi. Abarwayi bagomba gukurwa mukarere kanduye, bararuhutse, bakomeza gushyuha; Niba guhumeka bihagarara, bahita bakora guhumeka neza no gushaka ubuvuzi. Ku bw'impanuka yamenetse mu maso, yunamye n'amazi menshi, shakisha ubuvuzi mu manza zikomeye. Guhuza uruhu: kwoza amazi mbere, hanyuma woge neza ukoresheje isabune. Niba haraka, shakisha ubuvuzi. Ako kanya wombike umunwa niba winjiye wibeshye kandi ushake byihutirwa kwivuza.
Mugihe ukora ibikoresho bya barium, birakenewe gushimangira ingamba zo kurinda umutekano umutekano. Imyanda yose igomba kuvurwa hamwe na sulfate ya ferrous cyangwa sodium sulfate kugirango uhindure iminyururu yuburozi muri salfate nkeya.
Abakora bagomba kwambara kwigana masike yumukungugu, imiti yumutima imiti, imyenda ikingira imiti, na gants ya reberi. Irinde amasoko yumuriro nubushyuhe, kandi kunywa itabi birabujijwe rwose kumurimo. Koresha sisitemu yo guturika-ibikoresho bifatika. Irinde guhura na oxidants, acide, hamwe nibishingiro, cyane cyane n'amazi.
Kubika muri Kerosene na Paraffin yuzuye, gupakira mumacupa yikirahure hamwe no gufunga ikirahure, hamwe nuburemere bwa net ya 1Kg kumacupa, hanyuma yibanda mumasanduku yimbaho yatondekanye na padi. Hagomba kubaho ibintu "bisobanutse neza hamwe nubushuhe" ku kirandikiriza ibipakira, hamwe na label ya kabiri y "uburozi".
Ububiko mu bubiko bukonje, bwumutse, kandi buhumeka budahwitse. Irinde ubushyuhe n'umuriro, kubuza ubushuhe, no gukumira ibyangiritse. Ntuhure n'amazi, acide, cyangwa impfizi. Yatandukanijwe n'ibinyabuzima, bikangura, kandi byoroshye ibyayo byo kubika no gutwara abantu, kandi ntibishobora gutwarwa muminsi yimvura.
Mugihe cyumuriro, umusenyi wumye, ifu yumye cyangwa ifu yumye izirikana irashobora gukoreshwa muguhitamo umuriro, namazi, ya dydrocardomed ya hydrocarbon cyangwa ifuro ya halorocarbone (nka 1211 yo kuzimya umukiranutsi) ntabwo byemewe.
