| titleOfInvention | Semiconductor ceramic composite for secondary electron multiplying device |
| abstract | PURPOSE: To obtain stable operation in ultra-high vacuum environment by subjecting a semiconductor ceramic having a suitable composition ratio of zinc oxide-titanium oxide-copper oxide to a baking process. n CONSTITUTION: Zinc oxide, oxide copper and titanium oxide are prepared, and so blended as to obtain a semiconductor ceramic having a suitable composition ratio thereof. Then, the aforesaid materials are wet grindered and mixed, and further subjected to processes of dehydration, drying, pulverization and grading. A product so molded is baked in natural atmosphere, using an electric furnace, and a cylindrical semiconductor ceramic sample is thereby obtained. n COPYRIGHT: (C)1992,JPO&Japio |
