  • Patent number: 6197252
    Abstract: The invention relates to a method of removing water-insoluble binder from a porous article formed from pressed particulate material, such as tantalum powder. The invention provides a method capable of removing substantially all of the binder from the article for high purity applications, such as capacitor manufacture. The method comprises contacting the article with an aqueous solution of an agent which reacts with said binder to produce a water soluble derivative thereof whereby said binder derivative may be substantially dissolved in said solution. In a particular embodiment, the derivative is produced by hydrolysis of a fatty acid binder.
