　　预焙阳极是以石油焦、沥青焦为骨料，煤沥青为黏结剂制造而成，用作预焙铝电解槽作阳极材料。

　　这种炭块已经过焙烧，具有稳定的几何形状，所以也称预焙阳极炭块，习惯上又称为铝电解用炭阳极。用预焙阳极炭块作阳极的铝电解槽称预焙阳极电解槽，简称预焙槽，这是一种现代化的大型铝电解槽。

　　预焙阳极电解槽和阳极炭块几乎与现代炼铝方法同时诞生。1880年，美国的霍尔(Hall)和法国的埃鲁(Heroult)同时提出冰晶石-氧化铝溶解炼铝法。1888年，美国匹兹堡电解厂把这种炼铝方法应用于工业生产，建成了世界上最早的预焙阳极电解槽，所用阳极炭块以木炭作为原料，采用模压法生产，单个阳极横截面积只有8～10cm2，其质量指示也比较落后。之后，瑞士、法国、英国、德国等几个国家都使用了类似的预焙阳极，用电解法生产铝。

The pre-baked anode is made of petroleum coke and pitch coke as aggregates and coal pitch as the binder, and is used as the anode material for the pre-baked aluminum electrolytic cell.

　　This kind of carbon block has been roasted and has a stable geometric shape, so it is also called pre-baked anode carbon block, which is also called carbon anode for aluminum electrolysis. The aluminum electrolytic cell that uses the pre-baked anode carbon block as the anode is called the pre-baked anode electrolytic cell, referred to as the pre-baked cell, which is a modern large-scale aluminum electrolytic cell.

　　The pre-baked anode electrolyzer and anode carbon block were born almost at the same time as the modern aluminum smelting method. In 1880, Hall of the United States and Heroult of France simultaneously proposed a cryolite-alumina solution aluminum smelting method. In 1888, the Pittsburgh Electrolysis Plant applied this aluminum smelting method to industrial production and built the world’s earliest pre-baked anode electrolysis cell. The anode carbon block used was made of charcoal as raw material and produced by the molding method. The cross-sectional area of a single anode was only 8～10cm2, its quality indicator is also relatively backward. Since then, several countries including Switzerland, France, the United Kingdom, and Germany have used similar pre-baked anodes to produce aluminum by electrolysis.
