HIGH-PRESSURE DISCHARGE LAMP HAVING A CERAMIC DISCHARGE VESSEL, SINTERED BODY SUITABLE HIEREFOR, AND METHOD FOR PRODUCING THE SAID SINTERED BODY |
| 摘要 |
A high-pressure discharge lamp (1) is provided with a ceramic vessel (6) made from alumina which is doped with 100-800 ppm MgO, 200-1200 ppm ZrO2 and 10-300 ppm Y2O3. This improves the loading capacity of the ceramic. <IMAGE> |
