| titleOfInvention |
Reheating a beta-alumina article in an alkali metal atmosphere to improve its permeability |
| abstract |
A BETA-ALUMINA ARTICLE PERMEABLE TO SODIUM AND POTASSIUM IONS MADE BY HEATING A SINTERED ALPHA-ALUMINA ARTICLE IN THE PRESENCE OF SODIUM OR POTASSIUM SUFFERS FROM A LACK OF UNIFORMITY OF CONVERSION OF ALPHA-ALUMINA TO BETA-ALUMINA, PARTICULARY IN THE CENTER PORTION OF THE ARTICLE. THE UNIFORMITY IS GREATLY IMPROVED BY REHEATING THIS ARTICLE AT SIMILAR TEMPERATURES USED IN THE FIRST HEATING STEP IN AN ATMOSPHERE HAVING A LOWER CONCENTRATION OF SODIUM OR POTASSIUM THAN USED IN T HE FIRST HEATING STEP. FOLLOWING THIS SECOND HEATING STEP THE ARTICLE IS WASHED IN WATER. |
