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

The heat resistance of SiN 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 SiN.

The author also develops a new fabrication method for SiN 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 SiN nanoceramics is dependent on load stress; the results of his research are detailed in this book.
