| titleOfInvention | Preparation method of ceramic insulator for extremely cold regions |
| abstract | The invention relates to a preparation method of a ceramic insulator used in an extremely cold region, which is characterized by comprising the following steps: the weight percentage of each raw material is as follows: 70-95% of corundum powder, 5-30% of zirconia powder, 1-2% of additional magnesium oxide, 1-2% of additional titanium oxide, 4-6% of additional cerium oxide and 0.5-2% of additional samarium oxide, weighing the raw materials, and uniformly mixing the raw materials by using a ball mill to obtain a mixture; granulating and staling; forming and drying a blank; firing the blank to obtain a ceramic insulator support body; coating a glaze layer: and coating a frit glaze layer on the surface of the ceramic insulator support body, and sintering at 1000-1200 ℃ to obtain the ceramic insulator for the extremely cold region. The ceramic insulator prepared by the method can bear the impact of extremely low temperature of 50 ℃ below zero, does not crack or freeze damage, has good combination of the glaze layer and the support body, and has the characteristics of high low-temperature strength, aging resistance and good freeze-thaw resistance. |
