The phosphorus doped molybdenum oxide compound (P0.18Mo4.00O12.66). is
ostructural with molybdite was synthesized in the process of thermally
induced phase transformation of 12-molybdophosphoric acid. The synthe
sized phases (low and high temperature) and the precursor compound (e-
phase) have been characterized by thermal (DTA and TGA), X-ray powder
diffraction, electron scanning microscopy and spectroscopic (IR) metho
ds. The temperature dependence of electric conductivity sigma(omega-->
0) is discussed. It was concluded that the electronic conductivities o
f bronzes obtained from heteropolyacids are very similar to those of c
orresponding anhydrous polyacids.
