The ceramic particles in fly ash have three types of structures.

Sintering at a high temperature to fuse the ceramic particles together.

As the very hard ceramic particles expand, they grind up the body of the projectile, and thus neutralize it.

For example, a continuous matrix, and a dispersed phase of ceramic particles or fibers.

In simple terms, the researchers adapted this natural process by replacing the salt with ceramic particles in suspension.

As the water freezes (in a carefully controlled process), the ceramic particles are squeezed out into layers on the order of one micron thick.

Kyocera plans to get around the problem by using a special "Ecotone" toner mixture that includes microscopic ceramic particles.

Embedded ceramic particles successfully managed the "smell factor" during class and after, said Roger Muckenfuss, 35, center left.

This material is defined as: any of several materials consisting of a metal matrix with ceramic particles disseminated through it.

The system his team is developing uses a tightly packed bed of sand-like ceramic particles that can be heated and cooled very rapidly.
