まれる。The present invention has the general formula (KX-?1Iy)Tifi016(X
, y is the same as above), and the structure is as shown in FIG. The value of X shown in the general formula is determined by the amount of potassium contained in the potassium titanium bronze starting material. Crystallographically, a range of x = O ~ 2 is allowed, but since some potassium remains unreacted during the production of the starting material, the value of x = 1.0 ~ 1.3 is usually obtained. In the figure, y indicates the amount of Ni ion-exchanged with Ho, and is in the range of O<y≦0.7x. The lattice constant is x,
Although it changes somewhat depending on the change in y, a = 10.16 to 10

The higher the acid concentration and the higher the reaction temperature, the faster the processing speed, but if the concentration is too high or the temperature is too high, the starting material or target product will dissolve.
The reaction temperature is preferably 100''C or less.

The sample was heated on a hot water bath kept at 80°C to perform ion exchange between ゛ and Ho. After reacting for 10 days, a portion of the solution was taken and the amount of potassium eluted was determined by atomic absorption spectrometry. The phase of the precipitate was identified by powder X-ray diffraction. As a result, dark purple powder 1[1], J6. tT

There were 6 (2) people, c = 2.961 (1). The X-ray powder diffraction pattern of this product is shown in FIG. The reason why a resin container was used instead of a glass container was to avoid elution of potassium from the glass container in order to quantify potassium in the solution after the reaction. If there is no such purpose, it is sufficient to use a glass container.
