Embodiment 1
[0028] The manufacturing process of the present embodiment magnesium oxide composite sheet is:
[0029] (1) Dry magnesia powder and zirconia powder at 300°C for 30 minutes;
[0030] (2) Take 80g of magnesia powder and 20g of zirconia powder dried in step (1), mix the magnesia powder and zirconia powder evenly, add 10g of distilled water, stir evenly, and make a mixed slurry;
[0031] (3) Pressing the mixed slurry produced in step (2) into a tablet to make a magnesium oxide prefabricated tablet;
[0032] (4) Put the magnesium oxide prefabricated sheet in an oven, set the temperature at 200°C for 60 minutes, at 800°C for 30 minutes, and at 1300°C for 120 minutes to prepare the magnesium oxide sheet.
[0033] In this embodiment, the pressed abrasive tool used in step (3) is as figure 1 and 2 As shown, the pressed abrasive tool includes an upper indenter 1, a body 2, and a lower indenter 3, and at least two exhaust slots 4 are provided on the bottom side of the upper indenter 1...
