  • Vibratory calcination of inorganic oxide superconductor precursor powders
    Patent number: 4997810
    Abstract: An inorganic powder is vibrated while being calcined. The vibrations suspend the powder as in a conventional gas-fluidized system, without clumping, but without loss of fines. As applied to superconductor precursor powders, the treatment accelerates growth of the superconducting phase. The invention includes a novel furnace system for simultaneously heating and vibrating the powders.
