Abstract
Electro ceramics showing interesting electrical functions can be produced by industrial ceramics manufacturing processes. The processes consist of, in general, the unit operations such as weighing, mixing, crushing, firing and so on. And electric functions of electro ceramics as final product depend on the combination of each unit operations. Microscopically, the electric function of final product can be considered to subject to the basic particle size of working material in each unit operation. Therefore, it is necessary to elucidate unit operation loop of ceramics manufacturing process.
n this paper, the change of basic particle size along the unit operation loop, that is, hierarchy change is fundamentally discussed, and the evaluation method of the hierarchy change is presented by applying to powder compact process of ceramics manufacturing processes. As a result, the hierarchy change of basic particle in powder compact process is qualitatively shown by using the evolution method presented.
