気下で加熱する方法が知られている。<Prior art> The conventional methods for producing titanium carbonitride include: (1) heating a mixture of titanium carbide powder and titanium nitride powder at high temperature, and (2) heating a mixture of metallic titanium powder and carbon in a nitrogen atmosphere. There are known ways to do this.

とする必要があるが、金属チタン粉末は角状であるので
得られる粉末も角状となるという問題がある。However, in method (2), it is necessary to sufficiently form a solid solution between titanium carbide and titanium nitride.
This requires high-temperature heating of 000° C. or higher, and there is a problem that the particles become coarse. On the other hand, in method (2), in order to obtain fine particles of titanium carbonitride, it is necessary to make the raw material titanium metal into fine particles, but since metal titanium powder is angular, the resulting powder also has a problem. There is.

提案されている。Therefore, in order to solve these problems, we added amorphous carbon powder to anatase-type titanium oxide powder, wet-pulverized it, mixed it, and dried it in a nitrogen-containing atmosphere.
A method of performing ρ, carbonization, nitriding, and solid solution formation by heating at a temperature of 000°C (Japanese Patent Application Laid-Open No. 58-2136
No. 17), or by mixing titanium oxide powder and carbon powder and heating it in a nitrogen atmosphere with a predetermined nitrogen partial pressure.
A method has been proposed (Japanese Unexamined Patent Publication No. 106405/1983) in which reduction and carbonitriding are carried out by heating to 7 to 1727°C.
〈発明が解決しようとする問題点〉
しかしながら、上述した二つの改良方法においても次の

。In the case of the former (Japanese Unexamined Patent Publication No. 58-213617),
Because it is heated at 1700°C to 2000°C to remove residual oxygen, grain growth is unavoidable, and if the obtained titanium carbonitride is used as a raw material for powder metallurgy, the grain size will be large and the strength of the sintered body will decrease. There is a problem. On the other hand, in the case of the latter (JP-A No. 61-106405), it is necessary to control the nitrogen partial pressure during the reaction, but since degassing occurs from the raw materials during the reaction, the gas discharged from the reaction system There is a problem in that it is necessary to constantly analyze nitrogen and feed back the results to the nitrogen gas inlet of the reaction system to control the nitrogen flow rate, and that this management is extremely complicated.

The amount is necessary and sufficient to obtain +-xcO<X<1), but it is not determined simply by the target composition of titanium carbonitride, but is influenced by the type of raw materials, reaction conditions, etc. Therefore, this mixing ratio needs to be determined experimentally.
