摘要：

Crystalline powders of Li2ZrO3 were prepared by gelling ZrCl4 and CH3COOLi with NH4OH at 50-degrees-C, at different pH values (5, 7 and 8) and for different times (3, 12 and 24 h), then drying and calcining. Compacts from these powders were found sinter to higher densities than a commercial Li2ZrO3; their porosity at 1200-degrees-C was close to 3-mu-m and was suitable for blanket material applications. Tritium release as HTO begins at 300-degrees-C and reaches 73% at 400-degrees-C, a temperature much lower than that required for Li2O.
