講義概要

材料は,融体を経由して製造されることが多い。したがって,その物理化学的性質を理解することは,材料プロセスの設計およびその最適化を図るためには不可欠である。本講義では,金属および酸化物融体の熱力学および状態図を軸として,活量の使い方や状態図,とくに融体を含む三元系の状態図の読み方を習得することを目的とする。演習も多数行う。

Many materials are produced via the state of melts and thus understanding of physico-chemica

講義の目的

The term of 'melts' essentially means what the term of 'liquid' does and is often used, in particular, when one refers to the state of substances which are melted at high temperatures. In this usage, for example, liquid iron is a kind of melt but liquid water is not. Many materials are produced via the state of melts and thus understanding of physico-chemical properties of melts is essential to materials process designing and its optimisation. This lecture mainly centres upon thermodynamics and phase diagrams for metal and its oxide melts, and aims at learning how to use the activity and how to read phase diagrams, in particular, for ternary systems containing melts, through many exercises.
