摘要
Nasicon and Titzicon compositions have been obtained as powders or monolithic, optically clear gels by sol-gel processes. Variations of the synthesis method have been explored by changing the proportion of metal organic reagents and the hydrolysis rate. The structural evolution as a function of temperature can be correlated with the specific area variations: the Nasicon phase is gradually formed between 800 and 1050 degree C. The target compositions were achieved with only a small Zr deficiency.
