Abstract
The influence of changes in the nominal composition and preparation co nditions on the formation of Tl(1223) under a high isostatic gas press ure was studied. Optimization of the cation substitution allowed to in crease the phase purity, whereas substitution of small amounts of oxyg en by fluorine decreased the formation temperature of the Tl(1223) pha se and extended the temperature range favorable for grain growth. A tw o-step reaction involving substantial melting produced well shaped, pl ate-like grains.
