Title:
TITANIUM SUBOXIDE AND PROCESS FOR PRODUCING TITANIUM SUBOXIDE
Document Type and Number:
Japanese Patent JP2019167274
Kind Code:
A
Abstract:
To provide: a titanium suboxide that contains TiOwith a crystal structure that phase-transitions between a β phase and a λ phase, and can be manufactured at relatively low cost; and a process for producing titanium suboxide.SOLUTION: The titanium suboxide stores heat or releases heat by the action of pressure or heat, or light irradiation, and contains TiOhaving a crystal structure that undergoes phase-transition between a β phase and a λ phase, and has a specific surface area in the range of 1.15 m/g to 1.5 m/g. The process for producing titanium suboxide includes a step of hydrogen reducing a titanium raw material containing TiOhaving a specific surface area of 1.0 m/g to 10 m/g at 1100°C to 1300°C.SELECTED DRAWING: Figure 1
