te-trachloride)是指除去粗四氯化鋯的雜質(zhì)，產(chǎn)出純四氯化鋯的過程。碳化鋯、鋯英石或二氧化鋯氯化制得的四氯化鋯還含有相當(dāng)數(shù)量的FeCl3、AlCl3、 TiCl4、SiCl4、ZrOCl4和碳粉等雜質(zhì)，必須經(jīng)過深度除去方可用作生產(chǎn)海綿鋯的原料。提純方法主要有氫還原法和熔鹽提純法兩種，前者為歐洲一些國家和美國等所采用，后者為前蘇聯(lián)所采用。此外，還出現(xiàn)一種流態(tài)化提純法。（1）利用ZrCl4與TiCl4、SiCl4在相同溫度時存在不同蒸氣壓差，控制一特定溫度，使TiCl4、SiCl4和H2O先升華而除去；（2）利用氯化亞鐵或氯化亞鉻的高沸點(前者為1303K，后者為1573K)用氫氣將三價的鐵和鉻還原為二價。在ZrCl4升華溫度下(723-933K)·FeCl4、Gr-Cl2和ZrOCl2不升華留在殘遭中而和鋯分離</p><p> 熔鹽體系提純四氯化鋯的原理: </p> <p> 熔鹽體系提純四氯化鋯是利用四氯化鋯與堿金屬氯化物能形成低熔點共熔體這- -特性，將四氯 </p> <p> 化鋯不斷的溶解于該熔鹽體系中，使得低沸點雜質(zhì)在熔鹽表面蒸發(fā)掉,較高沸點雜質(zhì)(如Fe*. AlP* </p> <p> 等離子)伴隨著四氯化鋯的溶解,與熔鹽中堿金屬離子形成穩(wěn)定的復(fù)鹽而留在熔鹽內(nèi); </p> <p> FeCl,+KCl→KFeCl4 </p> <p> AlCl,+KCl→KAICl4 </p> <p> 再次加熱熔鹽，使四氯化鋯又蒸發(fā)出來并冷凝在冷凝器中，收集下來，即得到提純后的精四氯化鋯。 <p> 新熔鹽體系的建立:等摩爾的氯化鈉和氯化鉀與一定比例的四氯化鋯混合均勻裝人熔鹽爐內(nèi)， </p> <p> 加熱、升溫使其全部融化，熔化溫度在300C左右。此熔體很難形成，- -旦形成，熔體非常穩(wěn)定,粘 </p> <p> 度與水相似，此熔體四氯化鋯的溶解度非常大，此性質(zhì)非常有利于該方法的提純產(chǎn)能的提高，減小 </p> <p> 設(shè)備的投資。 </p>

儲存于陰涼、干燥、通風(fēng)良好的庫房。遠(yuǎn)離火種、熱源。包裝必須密封，切勿受潮。應(yīng)與酸類、胺類、醇類、酯類等分開存放，切忌混儲。儲區(qū)應(yīng)備有合適的材料收容泄漏物。 </p> <p> 四氯化鋯的合成方法按計量摩爾比稱取二氧化鋯和煅燒過的炭黑，混合均勻后放入瓷舟。將瓷舟置于瓷管中，在氯氣流中加熱到500℃進(jìn)行煅燒。用捕集器在室溫下收集產(chǎn)物。考慮到四氯化鋯在331℃升華，可用600mm長的管子，在300～350℃于氫氣流中將其重新升華，以除去氯化鋯中氧化物及三氯化鐵。四氯化鋯還有別的名稱嗎？遼寧本地四氯化鋯</p><p
