Tritigenic material based on lithium silicoaluminate and process for its preparation

摘要

This material includes a lithium silicoaluminate of formula: Li4+xAl4-3xSi2xO8 with 0<0<0.28, optionally doped with Na, K, Zn or a transition element. This material may be prepared by hydrolysis of a mixture of aluminium and silicon alkoxides and of lithium hydroxide, followed by drying and sintering. It can release tritium at temperatures of 300 DEG C. <IMAGE>
