style="text-indent:25px">含鋯的天然硅酸鹽ZrSiO4稱為鋯石（Zircon）或風信子石（hyacinth）***分布于自然界中，具有從橙到紅的各種美麗的顏色，自古以來被認為是寶石，印度洋中的島國斯里蘭卡盛產鋯石。1789年德國人M.H.Klaproth對鋯石進行研究時發(fā)現(xiàn)，將它與氫氧化鈉共熔，用鹽酸溶解冷卻物，在溶液中添加碳酸鉀，沉淀，過濾并清洗沉淀物，再將沉淀物與***共煮，然后濾去硅的氧化物，在濾液中檢查鈣、鎂、鋁的氧化物，均未發(fā)現(xiàn)，在溶液中添加碳酸鉀后出現(xiàn)沉淀，這個沉淀物不像氧化鋁那樣溶于堿液，也不像鎂的氧化物那樣和酸作用，Klaproth認為這個沉淀物和以前所知的氧化物都不一樣，是由Zirkonerde（鋯土，德文）構成的，不久，法國化學家de Morueau和Vauquelin兩人都證實M.H.Klaproth的分析是正確的，該元素拉丁名為Zirconium，符號認為Zr，中國譯成鋯，1808年，英國的H.Davy利用電流分解鋯的化合物，沒有成功，1824年瑞典的J.J.Berzelius首先用鉀還原K2ZrF6時制得金屬鋯，但不夠純，反應式為：K2ZrF6+4K=Zr+6KF，該反應也可用Na作還原劑，直到1914年，荷蘭一家金屬白熱電燈制造廠的兩位研究人員Lely和Ham bruger用無水四氯化鋯和過量金屬鈉同盛入一空球中，利用電流加熱500℃，取得了純金屬鋯。</p><p> 氟鋯酸鉀用途： </p> <p> 1.氟鋯酸鉀用做生產金屬鋯及二氧化鋯其他鋯化合物的原料及鎂鋁合金。用于電器材料、耐火材料、電真空技術材料、陶瓷和玻璃的生產等。 </p> <p> 2.氟鋯酸鉀用于制金屬鋯及其他鋯化合物，也用于鋁鎂合金、以及原子能工業(yè)和高級電器材料、火、陶瓷、搪瓷和玻璃的生產等。。 </p> <p> 3.氟鋯酸鉀用作催化劑和焊接劑，也用于光學玻璃、金屬鋯的制造。生產方法 </p> <p> 碳酸鉀法氫氟酸溶解二氧化鋯后，再與碳酸鉀反應，經蒸發(fā)、冷卻、結晶、烘干，即得成品。其ZrO2+6HF→2HF?ZrF4+2H2O2HF?ZrF4+K2CO3→K2ZrF6+C02↑+H2O。 </p> <p> 毒性 </p> <p> 如濺到人的皮膚上，表現(xiàn)出明顯的刺激作用，發(fā)生糜爛。比較高容許濃度為1mg/m3。采用戴防毒口罩、防護眼鏡，穿防塵工作服等防護措施，注意保護皮膚。防止有氟化氫和氯化氫排出，局部通風和***通風。工作人員要定期做胸廓、骨骼的x線照相?；佳例X、頜骨病和骨病的人，禁忌從事接觸此類化合物的工作。氟鋯酸鉀在使用的時候務必要帶上防塵口罩。</p><div
