随着电子技术的进步,钽在制造高质量、小型化的电解电容器方面获得了广泛的应用。据统计,资本主义国家在这方面的应用消耗了Ta_2O_5总产量的一半,其余的钽用于硬质合金刀具、化工容器衬里和高温合金。电解电容器用的钽粉一般是K_2TaF_7用钠还原的。高电压用的高纯钽粉是用电子束熔炼的铸锭经粉末化制成的。一般钽电容器的生产方法是用粉末冶金
With the advancement of electronic technology, tantalum has been widely used in the manufacture of high quality, miniaturized electrolytic capacitors. According to statistics, the capitalist countries have consumed half of the total Ta_2O_5 production in this area, while the rest of tantalum has been used in carbide cutting tools, chemical container linings and superalloys. Tantalum powder for electrolytic capacitors is generally K_2TaF_7 with sodium reduction. The high-purity tantalum powder for high voltage is made by pulverizing an ingot that is electron beam-melted. The general method of producing tantalum capacitors is powder metallurgy
