發(fā)現(xiàn)人：繆勒發(fā)現(xiàn)年代：1782年發(fā)現(xiàn)過(guò)程：1782年，德國(guó)的繆勒，從一種呈白而略帶藍(lán)的金礦里提出白色金屬樣物質(zhì)，即碲。元素描述：有結(jié)晶形和無(wú)定形兩種同素異形體。電離能。結(jié)晶碲具有銀白色的金屬外觀，密度，熔點(diǎn)452℃，沸點(diǎn)1390℃，硬度是（莫氏硬度）。不溶于同它不發(fā)生反應(yīng)的所有溶劑，在室溫時(shí)它的分子量至今還不清楚。無(wú)定形碲（褐色），密度，熔點(diǎn)±℃，沸點(diǎn)±℃。碲在空氣中燃燒帶有藍(lán)色火焰，生成二氧化碲；可與鹵素反應(yīng)，但不與硫、硒反應(yīng)。溶于硫酸、硝酸、氫氧化鉀和反應(yīng)鉀溶液。易傳熱和導(dǎo)電。元素來(lái)源：從電解銅的陽(yáng)極泥和煉鋅的煙塵等中回收制取。元素用途：主要用來(lái)添加到鋼材中以增加延性，電鍍液中的光亮劑、石油裂化的催化劑、玻璃著色材料，以及添加到鉛中增加它的強(qiáng)度和耐蝕性。碲和它的化合物又是一種半導(dǎo)體材料。元素輔助資料：碲與它的同族元素硫相比，在地殼中的含量少得多。碲成單質(zhì)存在的礦是極難找到的。碲在一般狀況下有兩種同素異形體，一種是晶體的碲，具有金屬光澤，銀白色，性脆，是與銻相似的；另一種是無(wú)定形粉末狀，呈暗灰色。碲在自然界有一種同金在一起的合金。1782年奧地利首都維也納一家礦場(chǎng)監(jiān)督牟勒從這種礦石中提取出碲。5N碲錠使合金組織明顯細(xì)化，具有強(qiáng)度高，塑性好，耐蝕好等優(yōu)異特性。</p><div
