Deformable Granule Production
A method of forming granules, the method comprising forming a suspension of a nanopowder such as a nano zirconia powder containing yttria. The powder is formed from a suspension, and freon is added directly to the suspension as an additive. The suspension is then granulated by spray freeze drying, and the freon subsequently removed by heat treatment. The voids left by the vacated freon provide meso, micro and macro flaws or structural defects in the granules.
