Embodiment 1
[0345] Tungsten hexachloride was dissolved in ethanol and dried at 130°C to produce tungsten oxide hydrate. It was heated at 550°C for 1 hour in a reducing gas atmosphere (argon / hydrogen=95 / 5 volume ratio), returned to room temperature once, and then heated at 800°C for 1 hour in an argon atmosphere to produce the target tungsten oxide powder.
[0346] As a result of identifying the crystalline phase by X-ray diffraction, the obtained powder was W 18 o 49 (WO 2.72 ) of the so-called Magnelli phase. The result of observing the shape of the powder by SEM is shown in Fig. 4(A) and (B). Among them, (A) is W 18 o 49 The 10,000-fold SEM image of (B) is the 3,000-fold SEM image.
[0347] Then, as shown in Fig. 4(A) and (B), needle-shaped crystals were observed. In addition, the powder had a powder resistance value of 0.085 Ω·cm measured under a pressure of 9.8 MPa, confirming good electrical conductivity.

Embodiment 2
[0351] The ammonium metatungstate aqueous solution was dried at 130° C. to obtain a powdery tungsten oxide compound. This was heated at 550° C. for 1 hour in a reducing atmosphere (argon / hydrogen=97 / 3 volume ratio), returned to room temperature once, and then heated at 800° C. for 1 hour in an argon atmosphere to produce tungsten oxide powder. As a result of identifying the crystalline phase by X-ray diffraction, it was observed that W 18 o 49 (WO 2.72) crystal phase. Thus, even if ammonium metatungstate aqueous solution is used for a tungsten compound starting material, the electroconductive particle equivalent to Example 1 can be produced. The powder resistance value measured under the pressure of 9.8 MPa of this electroconductive particle powder was 0.089 Ω·cm, and it was confirmed that favorable electroconductivity was obtained.
Embodiment 3
[0353] Cesium carbonate and tungstic acid were mixed in a mortar so that the molar ratio of Cs / W was 0.33. This was heated at 600° C. for 2 hours in a reducing gas atmosphere (argon / hydrogen=97 / 3 volume ratio). Then, after returning to room temperature once, heating in an argon atmosphere at 800°C for 1 hour, thereby producing Cs 0.33 WO 3 powder of conductive particles. The results of identification of the crystalline phase by X-ray diffraction, Cs 0.33 WO 3 It is a hexagonal tungstate alkali metal salt. The result of observing the shape of the powder of the obtained conductive particles by SEM is shown in FIG. 5 . Among them, Figure 5 is Cs 0.33 WO 3 10,000x SEM images of the.
[0354] Then, as shown in Fig. 5, crystals of hexagonal prisms were observed. The powder of the conductive particles had a powder resistance value measured at a pressure of 9.8 MPa of 0.013 Ω·cm, confirming good conductivity.
