[0300]Next, Examples of the invention will be described.
1. Production of Sintered Body (Zr—Nb Based)
Sample No. 1
[0301](1) First, a metal powder having a composition shown in Table 1 produced by a water atomization method was prepared. This metal powder had an average particle diameter of 4.05 μm, a tap density of 4.20 g / cm3, and a specific surface area of 0.23 m2 / g.
[0302]The composition of the powder shown in Table 1 was identified and determined by an inductively coupled high-frequency plasma optical emission spectrometry (ICP method). In the ICP analysis, an ICP device (model: CIROS-120) manufactured by Rigaku Corporation was used. Further, in the identification and determination of C, a carbon-sulfur analyzer (CS-200) manufactured by LECO Corporation was used. Further, in the identification and determination of O, an oxygen-nitrogen analyzer (TC-300 / EF-300) manufactured by LECO Corporation was used.
[0303](2) Subsequently, the metal powder and a mixture (an organic binder) of poly...
