Embodiment 1
[0047] Weighing SnO with a balance 2 1.50g, TiO 2 15.33g and BaCO 3 39.87g, put the raw material into a ball mill jar, the ratio of zirconium balls in the ball mill jar: raw material: alcohol is 4:1:1, ball mill for 24 hours, then dry the raw material, and grind the raw material through a 70-mesh sieve. Finally, the raw material was sintered at 1250°C for 2 hours to obtain the sintered product, and then the XRD was measured by the Japanese Rigaku in-situ analytical type X-ray diffractometer to observe that there were no impurities and peaks, see figure 1 Middle curve (a), figure 1 The XRD spectrogram of the sintered product that is the embodiment of the present invention 1~4 preparation, by figure 1 From the middle curve (a), it can be seen that there is no impurity peak in the sintered product prepared in Example 1.
[0048] The powder is ball milled for the second time. The diameters of the zirconium balls are 3mm, 1mm and 0.5mm respectively, and the mass ratio is 2:1...
Embodiment 2
[0055] Weighing SnO with a balance 2 3.03g, TiO 2 14.52g, BaCO 3 39.87g, put the raw material into a ball mill jar, the ratio of zirconium balls in the ball mill jar: raw material: alcohol is 4:1:1, ball mill for 24 hours, then dry the raw material, and grind the raw material through a 70-mesh sieve. Finally, the raw material was sintered at 1250°C for 2 hours to obtain the sintered product, and then the XRD was measured by the Japanese Rigaku in-situ analytical type X-ray diffractometer to observe that there were no impurities and peaks, see figure 1 Middle curve (b). Depend on figure 1 From the middle curve (b), it can be seen that there is no impurity peak in the sintered product prepared in Example 2.
[0056] The powder is ball milled for the second time. The ball milled zirconium balls are 3mm, 1mm, and 0.5mm. The ratio is 2:1:1, a total of 200g. Ketone 1:1, 25g each. After rolling for 24 hours, add 1g dispersant, 4g binder PVB, 2g plasticizer, and add appropria...
Embodiment 3
[0063] Weighing SnO with a balance 2 4.54g, TiO 2 13.71g, BaCO3 39.87g, put the raw materials into a ball mill jar, the ratio of zirconium balls in the ball mill jar: raw material: alcohol is 4:1:1, ball mill for 24 hours, then dry the raw materials, and grind the raw materials through a 70-mesh sieve. Finally, the raw material was sintered at 1250°C for 2 hours to obtain the sintered product, and then the XRD was measured by the Japanese Rigaku in-situ analytical type X-ray diffractometer to observe that there were no impurities and peaks, see figure 1 The middle curve (c), by figure 1 From the middle curve (c), it can be seen that there is no impurity peak in the sintered product prepared in Example 3.
[0064]The powder is ball milled for the second time. The ball milled zirconium balls are 3mm, 1mm, and 0.5mm. The ratio is 2:1:1, a total of 200g. Ketone 1:1, 25g each. After rolling for 24 hours, add 1g dispersant, 4g binder PVB, 2g plasticizer, and add appropriate am...
