氬氣(qi)是(shi)(shi)(shi)一種(zhong)惰(duo)(duo)性氣(qi)(qi)(qi)(qi)體，目前廣(guang)泛應(ying)(ying)用(yong)(yong)于工業行(xing)業，是(shi)(shi)(shi)一種(zhong)很(hen)有(you)用(yong)(yong)的(de)(de)(de)稀(xi)有(you)氣(qi)(qi)(qi)(qi)體，氬(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)性質十分(fen)不活(huo)潑，它既不能(neng)燃燒，也不能(neng)助燃，因此穩定(ding)性很(hen)好，氬(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)不會(hui)發生化(hua)(hua)學反(fan)應(ying)(ying)而爆炸(zha)，只有(you)可能(neng)因為科拉貝隆(long)推(tui)導公式的(de)(de)(de)壓(ya)(ya)強變化(hua)(hua)而爆炸(zha)。氬(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)罐很(hen)結實，也不會(hui)像煤氣(qi)(qi)(qi)(qi)罐那樣單片橫飛，ArF是(shi)(shi)(shi)有(you)的(de)(de)(de)，但溫度變化(hua)(hua)不大，一般情(qing)況下(xia)，甚至(zhi)高(gao)(gao)溫高(gao)(gao)壓(ya)(ya)下(xia)都沒有(you)問題。高(gao)(gao)純(chun)氬(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)的(de)(de)(de)國家(jia)執行(xing)標準(zhun)是(shi)(shi)(shi)GB/T10624—1995，質量要求達(da)到99.999%以上。氬(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)是(shi)(shi)(shi)采用(yong)(yong)空氣(qi)(qi)(qi)(qi)分(fen)離提氬(ya)(ya)(ya)，即將(jiang)(jiang)液(ye)(ye)化(hua)(hua)的(de)(de)(de)空氣(qi)(qi)(qi)(qi)進行(xing)精餾,獲(huo)得粗(cu)氬(ya)(ya)(ya).抽(chou)出(chu)粗(cu)氬(ya)(ya)(ya),經進一步提純(chun)可獲(huo)得高(gao)(gao)純(chun)氬(ya)(ya)(ya)，高(gao)(gao)純(chun)氬(ya)(ya)(ya)在(zai)半導體工業中(zhong)(zhong)(zhong)用(yong)(yong)作生產高(gao)(gao)純(chun)硅和(he)鍺晶體的(de)(de)(de)保護(hu)氣(qi)(qi)(qi)(qi)體；可用(yong)(yong)作系統清洗、屏(ping)蔽和(he)增(zeng)壓(ya)(ya)用(yong)(yong)的(de)(de)(de)惰(duo)(duo)性氣(qi)(qi)(qi)(qi)體；在(zai)化(hua)(hua)學氣(qi)(qi)(qi)(qi)相(xiang)沉積、濺(jian)射和(he)退火等工藝中(zhong)(zhong)(zhong)有(you)所(suo)應(ying)(ying)用(yong)(yong)。高(gao)(gao)純(chun)氬(ya)(ya)(ya)也可作為色譜載氣(qi)(qi)(qi)(qi).氬(ya)(ya)(ya)被廣(guang)泛用(yong)(yong)來充填弧光(guang)燈、熒光(guang)燈和(he)電子管；焊接(jie)保護(hu)氣(qi)(qi)(qi)(qi)；在(zai)鈦、鈷和(he)其他活(huo)性金屬的(de)(de)(de)生產中(zhong)(zhong)(zhong)用(yong)(yong)作屏(ping)蔽氣(qi)(qi)(qi)(qi)；在(zai)黑(hei)色冶金中(zhong)(zhong)(zhong)用(yong)(yong)于吹煉特種(zhong)鋼。    那么液(ye)(ye)氬(ya)(ya)(ya)又是(shi)(shi)(shi)什么呢？液(ye)(ye)氬(ya)(ya)(ya)是(shi)(shi)(shi)將(jiang)(jiang)高(gao)(gao)純(chun)氬(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)壓(ya)(ya)縮成液(ye)(ye)態氣(qi)(qi)(qi)(qi)，儲存(cun)于杜瓦罐中(zhong)(zhong)(zhong)。液(ye)(ye)氬(ya)(ya)(ya)使用(yong)(yong)時(shi)放出(chu)的(de)(de)(de)是(shi)(shi)(shi)氣(qi)(qi)(qi)(qi)相(xiang)的(de)(de)(de)，液(ye)(ye)氬(ya)(ya)(ya)儲存(cun)在(zai)杜瓦罐中(zhong)(zhong)(zhong)會(hui)有(you)一個(ge)自然(ran)增(zeng)壓(ya)(ya)的(de)(de)(de)過程，當它的(de)(de)(de)壓(ya)(ya)力過高(gao)(gao)時(shi)杜瓦罐會(hui)進行(xing)泄壓(ya)(ya)，在(zai)這(zhe)個(ge)自然(ran)增(zeng)壓(ya)(ya)和(he)泄壓(ya)(ya)的(de)(de)(de)過程中(zhong)(zhong)(zhong)，氬(ya)(ya)(ya)氣(qi)(qi)(qi)(qi)很(hen)容易就被釋(shi)放了。
