specific Embodiment approach 2
[0024] The process steps described in Example 2 and Example 1 are exactly the same, except for the following differences: take 30 grams of cobalt powder with a purity of 99.99%, and 3 grams of cobalt oxide powder with a purity of 99%, and put them in a jade vessel Mix and grind for 40 minutes, pour the ground mixed powder into the cobalt oxide tube, and keep compacting, the mixed powder accounts for 40% of the volume of the cobalt oxide tube; pour the cobalt powder into the upper half of the cobalt oxide tube, after compacting, Cobalt powder accounts for 60% of the volume of the cobalt oxide tube.
specific Embodiment approach 3
[0025] The process steps described in the present embodiment 3 are exactly the same as those in the embodiment 1, but there are the following differences: take 40 grams of cobalt powder with a purity of 99%, and 34 grams of cobalt oxide powder with a purity of 99%, and put them into a ceramic vessel Mix in medium and grind for 30 minutes. Pour the ground mixed powder into the cobalt oxide tube and keep compacting. The mixed powder accounts for 89% of the volume of the cobalt oxide tube. Pour the aluminum oxide powder into the upper half of the cobalt oxide tube. Finally, alumina powder accounts for 11% of the volume of the cobalt oxide tube.
