When the obtained sintered body was identified using XvA diffraction, only the diffraction lines of titanium carbide and aluminum oxide were observed. Further, the relative density of this sintered body was about 95%.

ものと考えられる。Table 1 also shows experimental results for other samples. As shown in the comparative example (sample 5), when only TiO2 is used as a titanium oxide source, the volumetric shrinkage during reaction is larger than when TiO2 or TiO is used, so the resulting composite sintered body It can be seen that the relative density of is low. On the other hand, by changing the titanium oxide used as a raw material with Ti2O3 or TiO, it is necessary to slightly raise the sample temperature at the time of ignition, but the relative density of the obtained sintered body can be increased in this order. This is because when lower oxides such as TiO are used, the amount of heat generated during the reaction is small (therefore some heating is required), but the volumetric contraction during the reaction is small, so the press pressure can be smoothly transmitted to the sample. Therefore, it is thought that the relative density of the obtained composite sintered body is high.

This occurs when O and TiC2 are used simultaneously. Such a method of using two or more types of titanium oxides is useful when it is desired to change the ratio of Al20G and TiC during composite sintering or when it is desired to control the heating temperature. Therefore, the heating temperature of sample 3 was 500℃ to 350℃ compared to sample 1.
The heating temperature of Sample 4 was 30% lower than that of Sample 2.
The temperature has decreased from 0°C to 200°C. This is TiO2
This is the effect of increasing the reaction heat by mixing in the molded body.

When only Ti203 is used, the volume shrinkage during reaction is slightly larger than when Ti203 or TiO is used as a raw material, so the relative density of the resulting composite sintered body is lower than that of other samples. You can see that it's a little low. and T 20 CI
Although it is necessary to slightly raise the sample temperature at the time of ignition by changing TiO and the monohydritanium acid used, the relative density of the obtained sintered body increases in this order.
