- Cubic aluminum nitride, cubic gallium nitride, and cubic indium nitride have excellent properties such as high hardness, high thermal conductivity, high temperature properties, and high chemical resistance. Therefore, it is used for electronic circuit boards and the like. Also, due to the large bandgap, it is attracting attention as a material for short-wavelength light-emitting diodes. It is known that aluminum nitride, gallium nitride, and indium nitride have a hexagonal wurtzite structure under a normal temperature and normal pressure environment and take a cubic system as a metastable system. Cubic nitrides are not usually obtained under rolling.

- the particles are bonded together without changing the crystal structure of the raw material fine particles.
- a hexagonal nitride material is changed into a cubic structure by colliding with a shock force of 4 [GPa] or more.
- the present invention is greatly characterized in that such a structural change of the ceramic material can be brought out with a small impact force of 10 [GPa] or less (impact force of 4 [GPa]). This is thought to be due to the use of the impact force to collide the ceramic powder itself as the raw material.
- a nitridation aluminum powder having a urethane ore structure 300 mesh, a particle size of about 0.5 / m: manufactured by Fluid Chemical Co., Ltd. was used.

- a peak not found in the raw material powder appears around 26> 44 °. This peak is due to cubic A 1 N. That is, a change in crystal structure (change from hexagonal system to cubic system) occurred during film formation by the aerosol deposition method.
- the intensity ratio between the cubic peak and the hexagonal peak varies depending on the deposition conditions. Assuming that the crystal grains in the film are of the same size and oriented in random directions, the peak intensity is considered to indicate roughly the abundance in the film. Therefore, A film was formed by changing the gas flow rate and the deposition time, and its X-ray analysis was performed. ⁇ ⁇ ⁇
- the peaks of the film show not only cubic peaks but also hexagonal peaks at the same positions as the powder peaks. It is a film in which a crystal and a cubic nitride are mixed. From this, it is possible to obtain a group 13 nitride in which a hexagonal crystal structure and a cubic crystal structure are mixed at an appropriate ratio by adjusting the pressure at the time of particle collision. Further, a Group 13 nitride film in which a hexagonal crystal structure and a cubic crystal structure are mixed at an appropriate ratio can be fixed on an extremely thin glass plate or metal plate.

Becomes possible.
- the impact force of 4 [GPa] or more required to change the crystal structure of the group 13 nitride into a cubic system is obtained by using an aerosol. This is achieved by setting the particle velocity at the time of spraying to 300 ms or more, and is an index when designing the equipment.
