发明名称 Process for producing powder metallurgy compacts free from binder contamination and compacts produced thereby
摘要 Metal powders are pressed into compacts more readily through the addition of a minor percentage of dimethyl sulfone binder. Dimethyl sulfone may be dry-blended with the metal powder by mixing it in the form of a powder, or it may be wet-blended by first dissolving it in a suitable solvent, then adding it to the metal powder and evaporating the solvent. Dimethyl sulfone may be almost completely removed from compacts pressed from tantalum, etc., either by vacuum distillation or by water leaching, to leave compacts uncontaminated by the binder and suitable for further processing into capacitor anodes, etc.
