Abstract
Experimental results by means of very precise X-ray goniometry on Pb 3P2xV2 (1-x) O8 system are given. They clearly show that there is no smearing of the order of transitions, x varying from 0 to 1, but a spreading of the critical temperature and of the rate of transformation, i.e. the volumic ratio between the high and low temperature phases. The interfaces between the two phases are describedKeywords
