Abstract
The sintered material includes a powder-derived material containing one or both of a nitride and an oxynitride, each of which contains at least one first metal element selected from the group consisting of group 4 elements, group 5 elements and group 6 elements in the periodic table, the rate y1/x1 of the atomic ratio y1 of non-metal element atoms in the powder-derived material to the atomic ratio x1 of metal element atoms therein is greater than 1, and the powder-derived material has a cubic structure.

A sintered material comprising:
- a powder-derived material containing one or both of a nitride and an oxynitride, each of which contains at least one first metal element selected from the group consisting of group 4 elements, group 5 elements and group 6 elements in the periodic table,
- the rate y1/x1 of the atomic ratio y1 of non-metal element atoms in the powder-derived material to the atomic ratio x1 of metal element atoms therein being greater than 1, and
- the powder-derived material having a cubic structure.
A powder containing:
- one or both of a nitride and an oxynitride, each of which contains at least one first metal element selected from the group consisting of group 4 elements, group 5 elements and group 6 elements in the periodic table,
- the rate y1/x1 of the atomic ratio y1 of non-metal element atoms in the powder to the atomic ratio x1 of metal element atoms therein being greater than 1, and
- the powder having a cubic structure.
