Method for preparing Pb-β"-alumina ceramic |
| abstract |
A process is disclosed for preparing impermeable, polycrystalline samples of Pb-β"-alumina ceramic from Na-β"-alumina ceramic by ion exchange. The process comprises two steps. The first step is a high-temperature vapor phase exchange of Na by K, followed by substitution of Pb for K by immersing the sample in a molten Pb salt bath. The result is a polycrystalline Pb-β"-alumina ceramic that is substantially crack-free. |
