| Outline of Final Research Achievements |
In order to achieve the control of flame synthesis by clustered microflames, the temperature, time and gas composition during particle travel in the synthesis field were measured at varied parameters of the distance between the fuel gas jets and the flow rate of the fuel and air jets. Then, the main part of the method of controlling flame synthesis was clarified in the present research project, particularly owing to obtaining the temperature histories of the raw material particles by measuring the velocity and temperature distribution, and revealing the complex three-dimensional structure of the clustered microflames by applying the CT method to the chemiluminescence from the flame front. Furthermore, by achieving highly reductive gas composition where material particles were introduced, the present project succeeded in the reduction synthesis of fine particles, which demonstrated its technical achievements most clearly.

拡散が支配的となる微小スケールでの燃焼現象の解明に関する進展は、本研究成果の学術的意義と言える。また、その解明により成された燃焼制御は燃焼利用の高度化につながり、例えば本研究では、火炎により酸化チタンから低次酸化チタンの還元合成に成功し、その技術的・社会的意義の一端が示された．低次酸化チタンは，省エネ効果のある外壁塗料、肌に優しく安全な化粧品原料、燃料電池やバッテリーなどの電極材料としても期待されている。この新たな合成手法を用いることで、従来の手法では合成できなかった様々な新材料の開発につながると期待される。
