摘要： Titanium-containing metal is extracted from its oxide(s) by way of redox chemical reaction with a reducing metal. Specifically, an intimate mixture of the reducing metal and the titanium-containing oxide(s) is produced, in a preferred embodiment, by forming a metal-ceramic composite material featuring these two constituents. In a preferred embodiment, the composite body is made by infiltrating the reduced metal in molten form, into a permeable mass containing the titanium-bearing oxide(s). Concurrently or subsequent to infiltration, the redox reaction is carried out to transform the composite material, thereby forming a complex intimate mixture containing one or more oxides of the reducing metal, a titanium-containing metal, which could include an alloy of titanium with the reducing metal and/or one or more intermetallic compounds of titanium and the reducing metal, and possibly also some residual reducing metal, which itself possibly contains some titanium metal. One technique for removing the titanium-containing metal is to then comminute the transformed composite material while the metal constituent is still molten, such as by high speed shearing. The dispersed ceramic constituents can then be permitted to separate, and the metal component containing the titanium can simply be decanted.
摘要翻译：通过与还原金属的氧化还原化学反应从其氧化物中提取含钛金属。具体地说，在优选的实施方案中，通过形成具有这两种成分的金属 - 陶瓷复合材料，制造还原金属和含钛氧化物的紧密混合物。在一个优选实施例中，复合体通过将熔融形式的还原金属渗透到含有含钛氧化物的可渗透物质中制成。在渗透的同时或之后，进行氧化还原反应以转化复合材料，从而形成含有还原金属的一种或多种氧化物的复合的紧密混合物，含钛金属，其可以包括钛与还原剂的合金金属和/或一种或多种钛和还原金属的金属间化合物，以及可能还有一些剩余的还原金属，其本身可能含有一些钛金属。一种用于除去含钛金属的方法是在金属成分仍然熔融时，例如通过高速剪切使粉末转化的复合材料粉碎。然后可以允许分散的陶瓷成分分离，并且可以简单地倾析含有钛的金属组分。
