In order to produce aluminium oxide beads, an acid aluminium oxide sol or an acid aluminium oxide suspension is converted into droplets by a vibrating nozzle plate and pre-solidified after the formation of a bead shape by laterally blowing gaseous ammonia and then coagulated in an ammonia solution.

Process for producing aluminum oxide beads

An apparatus for concentrating and solidifying a salt solution includes a vessel for containing the salt solution having an exposed surface, the vessel having a generally open upper portion, a cover for sealing the generally open upper portion of the vessel and having a generally hood shaped portion, the cover including at least one inlet conduit for admitting the salt solution to the vessel and a discharge conduit for vapor, and a magnetron for generating microwaves for heating the solution in the vessel. A microwave waveguide is disposed between the magnetron and the vessel and incorporates the cover, for directing microwaves from the magnetron into the vessel, the waveguide transitioning within the cover from the generally hood shaped portion into a horn having a variable cross-section and/or variable vertical spacing with respect to the vessel. This structure enables microwaves to be radiated directly onto the exposed surface of the salt solution in the vessel.

Method for producing stabilized zirconium oxide powder

To manufacture spherical particles out of liquid phase with a narrow grain spectrum using melting temperatures of up to 1500.degree. C. by generating droplets by means of vibrating nozzles, the liquid phase, the nozzle and the drop distance for the droplets are maintained at a constant temperature of 1.degree. to 10.degree. C. above the melting temperature of the liquid phase until the spherical shape of the falling droplets has stabilized. The particles must then be abruptly chilled.
