ABSTRACT:
Porous ceramic particles can be fragmented by generating a gas inside the pores at a sufficient pressure to cause the particles to be fragmented. The preferred way of generating the pressure is by immersing the particles in a liquid that at ambient temperatures and pressures is a gas until the liquid is absorbed into the pores and thereafter rapidly changing the conditions such that the liquid becomes a gas resulting in explosive fragmentation of the ceramic particles.
