形成多孔陶瓷颗粒的方法
摘要：
一种形成多个多孔陶瓷颗粒的方法可包括利用在分批模式中实施的喷雾流态化形成工艺形成所述多个多孔陶瓷颗粒。所述分批模式可包括至少两个批次喷雾流态化形成循环。利用所述喷雾流态化形成工艺所形成的所述多个多孔陶瓷颗粒可包括至少约0.01cc/g并且不大于约1.6cc/g的平均孔隙率。利用所述喷雾流态化形成工艺所形成的所述多个多孔陶瓷颗粒可进一步包括至少约200微米并且不大于约2000微米的平均粒径。所述多个多孔陶瓷颗粒的每一陶瓷颗粒可包含包括芯区和覆盖所述芯区的分层区的截面结构。
摘要（英）：

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.
