熔鹽電解爐如何分解電壓
熔鹽電解爐如何分(fen)解(jie)電(dian)壓呢?為什(shen)么在(zai)(zai)正(zheng)常生產條(tiao)件(jian)下電(dian)解(jie)的(de)結(jie)果主要是(shi)氧化稀土(tu)被分(fen)解(jie),在(zai)(zai)陰極之上析出稀土(tu)金屬(shu),在(zai)(zai)陽極上放出CO2與CO,這是(shi)由于在(zai)(zai)電(dian)解(jie)生產的(de)正(zheng)常條(tiao)件(jian)下,電(dian)介(jie)質各成份是(shi)有不(bu)同的(de)分(fen)解(jie)電(dian)壓。
眾所周知,如果用一(yi)個直流電(dian)(dian)(dian)(dian)(dian)源串聯(lian)一(yi)個食鹽(yan)電(dian)(dian)(dian)(dian)(dian)解槽和(he)一(yi)只(zhi)小(xiao)(xiao)燈泡,并(bing)構成一(yi)個回(hui)路(lu),實(shi)驗表明(ming),當(dang)電(dian)(dian)(dian)(dian)(dian)壓不(bu)夠高(gao)時,小(xiao)(xiao)燈泡不(bu)亮,這(zhe)說明(ming)電(dian)(dian)(dian)(dian)(dian)路(lu)中(zhong)幾乎沒(mei)有電(dian)(dian)(dian)(dian)(dian)流通過(guo),也就是(shi)說在電(dian)(dian)(dian)(dian)(dian)介槽的兩極上幾乎沒(mei)有電(dian)(dian)(dian)(dian)(dian)離現象,只(zhi)有當(dang)外加(jia)電(dian)(dian)(dian)(dian)(dian)壓達到一(yi)定的數值(zhi)之后,熔鹽(yan)電(dian)(dian)(dian)(dian)(dian)解爐才能進行(xing)電(dian)(dian)(dian)(dian)(dian)解。
這個為了保(bao)證熔(rong)鹽電(dian)(dian)解(jie)爐的物(wu)質(zhi)分解(jie),并在電(dian)(dian)極上獲(huo)得電(dian)(dian)解(jie)產物(wu)所需要的較低電(dian)(dian)壓叫做分解(jie)電(dian)(dian)壓,不同的物(wu)質(zhi)具有不同分解(jie)電(dian)(dian)壓。
以上便是熔(rong)鹽電解爐分(fen)解電壓的簡單(dan)介紹了。
