METHOD OF FORMING POROUS CERAMIC PARTICLES

摘要

A method of forming a plurality of porous ceramic particles may include forming the plurality of porous ceramic particles using a spray tluidization forming process conducted in a batch mode. The batch mode may include at least two batch spray fluidization forming cycles. The plurality of porous ceramic particles formed by the spray fluidization forming process may include an average porosity of at least about 0.01 cc/g and not greater than about 1.6 cc/g. The plurality of porous ceramic particles formed by the spray tluidization forming- process may farther include an average particle size of at least about 200 microns and not greater than about 2000 microns. Each ceramic particle of the plurality of porous ceramic particles may include a cross-sectional structure including a core region and a layered region overlying the core region.
