Published: with international search report (Art. 21(3)) (54) Title: POROUS CERAMIC PARTICLES AND METHOD OF FORMING POROUS CERAMIC PARTICLES (57) : A porous ceramic particle may have a particle size of at least about 200 microns and not greater than about 4000 microns. The porous ceramic particle may further have a particular cross-section that may include a core re- 522A gion and a layered region overlying the core region. The layered region may in- clude overlapping layered sections surrounding the core region. The core region 524A may include a core region composition and a first layered section may include a 5248 first layered section composition. The first layered section composition may be different than the core region composition. FIG. 5
