Abstract
A method for forming particles having a ridge portion includes inducing flow of a slurry of particles and a reactant through one or more orifices, detaching an amount of the slurry from the slurry flow following exit from the one or more orifices, the detached amount forming a slurry body, forming the slurry body into a particle shape, contacting the particle shaped slurry body with a coagulation solution to form a stabilized particle having the ridge portion, and drying and/or sintering the particle having the ridge portion.
