Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
127 words
AN IMPROVED METHOD FOR SUBSTITUTING POTASSIUM IONS FOR SODIUM IONS IN A CRYSTALLINE STRUCTURE COMPRISING A STRUCTURAL LATTICE AND SODIUM IONS WHICH MIGRATE IN RELATION TO SAID LATTICE UNDER INFLUENCE OF AN ELECTRIC FIELD, AT LEAST A MAJOR PROPORTION OF SAID LATTICE CONSISTING OF IONS OF ALUMINUM AND OXYGEN IN CRYSTAL LATTICE COMBINATION, SAID METHOD COMPRISING HEATING SAID CRYSTALLINE STRUCTURE TO A TEMPERATURE IN EXCESS OF ABOUT 900*C. CONTACTING SAID STRUCTURE WITH A SOURCE OF POTASSIUM ION HEATED TO A TEMPERATURE ABOVE ABOUT 900*C. AND ESSENTIALLY EQUAL TO THE TEMPERATURE OF SAID CRYSTALLINE STRUCTURE, AND MAINTAINING SAID STRUCTURE AND SAID SOURCE OF POTASSIUM ION AT A TEMPERATURE ABOVE ABOUT 900*C. UNTIL AT LEAST ABOUT 50% OF THE SODIUM IONS IN SAID STRUCTURE ARE REPLACED BY POTASSIUM IONS.
