In this book, improvements in the heat resistance of silicon nitride (Si N ) ceramics using grain boundary control and in plasticity at high temperatures using grain size control in order to reduce the cost of shaping Si N are described.

The heat resistance of Si N is improved by mixing a slight amount of sintering additive as an impurity into the original material powder. The author presents his findings on the high heat resistance of Si N .

The author also develops a new fabrication method for Si N nano-ceramics that produces high plastic formability. The method developed offers two improved points in grinding and sintering processes. The author found that the plastic formability of Si N nanoceramics is dependent on load stress; the results of his research are detailed in this book.
