Latest Patents

Yaroshenko holds a patent for a method of forming substantially spherical ceramic beads. This method involves conveying an aqueous ceramic slurry to a nozzle tip that is immersed in an inert water-immiscible fluid layer. The nozzle tip is strategically spaced from a rotating disk, which creates a shear force that dislodges droplets of the slurry into the immiscible fluid layer. The droplets then assume a spherical shape and a mono-modal size distribution. Once in the aqueous gelling solution, these droplets are converted into rigid beads. The preferred embodiment of this invention allows for the recovery, washing, and sintering of the beads to achieve a density greater than about 98% of theoretical density and a sphericity exceeding 0.95. This method is particularly useful for fabricating zirconia-containing beads with diameters ranging from about 0.1 mm to about 2.0 mm.
