摘要： A method for producing a metal by an electrolytic process using an yttria-containing porous ceramic body as a diaphragm is provided; the calcium formed by electrolysis cannot pass through the diaphragm, hence the back reaction can be effectively inhibited. Preferably, to be used is a diaphragm comprising a porous ceramic body having a purity of yttrium of 90 mass % or more (more preferably, 99% or more), a porosity of 1% or more and a pore diameter of 20 µm or less, and having a thickness of 0.05-50 mm and a metal halide is used as the electrolytic bath. The method can be utilized for producing metals such as calcium or rare earth elements, in particular. For example, when the method is applied to the production of calcium, metallic calcium can be produced with ease and at low cost without the need for enormous heat energy
摘要翻译：提供一种通过使用含氧化钇多孔陶瓷体作为隔膜的电解方法来制造金属的方法。通过电解形成的钙不能通过隔膜，因此可以有效地抑制反向反应。优选使用的是包含钇的纯度为90质量％以上（更优选为99％以上）的多孔陶瓷体的膜片，1％以上的孔隙率和20μm以下的孔径，并且具有0.05-50mm的厚度和金属卤化物用作电解浴。该方法特别可用于生产诸如钙或稀土元素的金属。例如，当该方法应用于钙的生产时，可以容易且低成本地生产金属钙，而不需要巨大的热能

摘要： A mixed molten salt containing CaCl 2 and NaCl is held in the reactor cell 1 at a temperature not more than 600 °C. TiCl 4 which is of a Ti raw material is introduced into the reactor cell 1 while Na is introduced into the reactor cell 1. Na introduced into the reactor cell 1 is replaced by Ca, Ca is dissolved in the molten salt, Ca reduces TiCl 4 introduced into the reactor cell 1, and thereby Ti particles are generated. The generated Ti particles are introduced to a separation cell 2 along with the molten salt, and the Ti particles and Na are separated from the molten salt. The residual molten salt is introduced to an electrolytic cell 3 to generate Na by high-temperature electrolysis at the temperature more than 600 °C. The generated Na is returned to the reactor cell 1 to replenish Na consumed in the reactor cell 1. The highly reactive Ca is not directly handled, and Na which is easy to handle is used in a circulating manner. Therefore, the Ti or Ti alloy can economically be produced by Ca reduction.
摘要翻译：含有CaCl 2和NaCl的混合熔融盐在不高于600℃的温度下保持在反应器单元1中。将作为Ti原料的TiCl 4引入到反应器单元1中，同时将Na引入到反应器单元1中。将引入到反应器单元1中的Na用Ca代替，将Ca溶解在熔融盐中，将Ca引入到将TiCl 4引入到生成电抗器单元1，并由此生成Ti颗粒。产生的Ti颗粒与熔融盐一起被引入分离单元2，并且Ti颗粒和Na与熔融盐分离。通过在600℃以上的温度下进行高温电解，将剩余的熔融盐引入电解槽3中以产生Na。产生的Na返回到反应器电池1中以补充反应器电池1中消耗的Na。不直接处理高反应性Ca，并且易于处理的Na以循环方式使用。因此，通过Ca还原可以经济地生产Ti或Ti合金。
