电容器钽粉是以钽为基,将碳、氮、硫中的至少两种元素按总含量为100～10000ppm加入钽粉中,其中硫含量为50ppm。最好还含有2～400ppm的磷,碳、氮、硫的总量为150～300ppm,其中硫至少为75ppm。碳、氮、硫以等摩尔加入或硫含量稍高于或等于碳、氮的总量。 用本法制成的钽粉可提高电容器的比电容,减 Capacitor Tantalum powder is based on tantalum, carbon, nitrogen, sulfur in the total content of at least two elements added to 100 ~ 10000ppm tantalum powder, wherein the sulfur content of 50ppm. Preferably, it contains from 2 to 400 ppm of phosphorus, carbon, nitrogen and sulfur in a total amount of from 150 to 300 ppm with sulfur of at least 75 ppm. Carbon, nitrogen and sulfur are added in equimolar amounts or the sulfur content is slightly higher than or equal to the total amount of carbon and nitrogen. Tantalum powder made with this method can increase the specific capacitance of the capacitor, minus
