Abstract:
A method for forming rod-shaped particles includes inducing flow of a slurry of particles and a reactant through one or more orifices and into a coagulation solution, wherein the slurry exiting the one or more orifices is a continuous uninterrupted stream, coagulating the reactant in the coagulation solution to form stabilized rods, drying the stabilized rods and reducing a length of the dried stabilized rods.
