Abstract Based on some electrical properties (resistivity, dielectric constant and pyroelectric
current) measured between 40 and 300 C, combined with the DTA thermogram in the same
temperature range, we observed two structural phase transitions in ammonium purpurate
(APP)“murexide'C 8 H 4 O 6 H 5· NH 4 at temperatures of about 100 and 257 C.
