Abstract
Recently, The ceramics which show interesting electric, magnetic and optic functions are used and taken notice in various fields. Then, electro ceramics manufacturing process becomes important in industry. The electoro ceramics manufacturing process consists of various kinds of unit operation such as weighing. mixing, crushing, firing and so on. Electrical properties of electro ceramics as final product depend upon each unit operation. However, the thermophysical relation between them has not yet been elucidated up to now.
Then in this paper, the relation between intermediate or final material properties and the operation conditions of electro ceramics maunfacturing process is discussed from the view point of thermophysics. And it can be point out that thermophysical three concepts such as entropy energy, free energy and carnot cycle can be effectively applied to elucidate the relation mention above electro ceramics manufacturing process.
