Embodiment 2
[0056] Except that the formula is different from Example 1, the process of this example is basically the same as Example 1.
[0057] Weigh the corresponding raw materials according to the ratio of the green body formula in Table 3, and add them to the ball mill for grinding. The grinding time is 26 hours. At high temperature, the slurry turns into powder. Afterwards, the green body is made to the same as that of Example 1 until the dotting process. The sintering temperature of this embodiment is 1200°C high-temperature rapid sintering for 75 minutes.

Embodiment 3
[0065] Except that formula is different from Example 1, the process of this example is the same as Example 1.
[0066] Weigh the corresponding raw materials according to the proportion of the body formula in Table 5, add them to the ball mill for grinding, and the grinding time is 20 hours. After the ball milling, unload the mud, pass the mud through a 200-mesh filter, and then inject the mud into the spray tower through the pipeline. At high temperature, the slurry turns into powder. Afterwards, the green body is made to the same as that of Example 1 until the dotting process. The sintering temperature of this embodiment is 1300°C high-temperature rapid sintering for 60 minutes.
