Embodiment 1
[0043] (9) NaNbO obtained in the above-mentioned comparative example 1 step (8) 3 Ceramic powder a was ball-milled for 6h to obtain NaNbO with better dispersibility 3 Nano powder b, see SEM image of powder b figure 1 -b, see the XRD pattern of powder b figure 2 .
Embodiment 2
[0045] (10) NaNbO with better dispersibility obtained in the above-mentioned step (9) of Example 1 3 The nano-powder was molded under a pressure of 150 MPa, and a cylindrical sample with a diameter of 11.5 mm and a thickness of 1.5 mm was formed. Then, using a double crucible seal, add NaNbO 3 The ceramic powder was used as a protective atmosphere, and the temperature was raised to 650°C at a heating rate of 7°C / min at room temperature, without the heat preservation process, and then increased to 950°C at a temperature increase rate of 3.5°C / min, without the heat preservation process, and continued to 3 The heating rate of ℃ / min was increased to 1150 ℃ and kept for 2 hours, then cooled to 1000 ℃ at a rate of 10 ℃ / min, without the heat preservation process, continued to cool down to 800 ℃ at a rate of 3.5 ℃ / min, and cooled with the furnace for about 7 hours Then take out the sample. Obtained containing NaNbO 3 Single-crystal grained ceramic body c, of which the single-crysta...
