の焼結体の密度は５．２５ｇ／−であった。Examples Example 1 Zirconium powder with a particle size of 10 μm or less as a starting material,
Using titanium dioxide (TiO2) powder with an average particle size of 1 μm and carbon black made from acetylene, the mixture was mixed at a molar ratio of 1:1:0.9, and then a diameter of 10 mm was obtained.
, was press-molded into a columnar shape with a height of 10 mm. This molded body was sintered using a uniaxial pressure vacuum hot press using a mold made of silicon carbide. The molded body was ignited by energizing the tungsten filament. The sample was placed at room temperature, in a vacuum (1+++ mHg) atmosphere, and under a pressure of O, 1 GPa, and the ignition heater was energized to start the reaction. When the obtained sintered body was identified using X-ray diffraction, only the diffraction lines of titanium carbide, tetragonal zirconium oxide, and monoclinic zirconium were observed. This X-ray diffraction revealed that tetragonal zirconium oxide and monoclinic zirconium were contained in a ratio of approximately 1:1. The density of this sintered body was 5.25 g/-.

Based on the reduction of 2, the reduced Ti metal (presumably melted into a liquid) reacts with C to form Ti.
It becomes C. Because the reaction heat at this time is large, no external heating is required (but the sample becomes high temperature (up to about 2000'C) and is pressurized, so ZrO2 particles and TiC particles sinter and form a ZrO2-TiC composite. A sintered body is obtained.
