Abstract

Controlled release ceramic particles, processes for their preparation, controlled release ceramic particles prepared by such processes, compositions comprising such controlled release ceramic particles and methods of using controlled release ceramic particles are described. In one form each of the controlled release ceramic particles has an active material(s) substantially homogeneously dispersed throughout the particles, wherein the active material(s) is capable of being released from said particles, and the active material(s) in said particles is substantially protected from degradation until release of the active material(s) from the particles.
