In this book, improvements in the heat resistance of silicon nitride (Si 3 N 4 ) ceramics using grain boundary control and in plasticity at high temperatures using grain size control in order to reduce the cost of shaping Si 3 N 4 are described.   The heat resistance of Si 3 N 4 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 3 N 4 .   The author also develops a new fabrication method for Si 3 N 4 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 3 N 4 nanoceramics is dependent on load stress; the results of his research are detailed in this book.
