heal.abstract	Aluminum-pillared montmorillonite (PILC MM) was doped with 12-tungstophosphoric acid hexahydrate (WPA-6) by the Solgel method. Using broad band dielectric relaxation spectroscopy (DRS), electrical properties of the obtained material were investigated. Thermally stimulated depolarization current technique was also used due to its high sensitivity and high resolving power. It has been established that pillared montmorillonite doped with WPA-6 (H3PW12O40 center dot 6H(2)O) shows conductivity higher than that of the pure components. Phase transition, which in WPA-6 takes place above 50 degrees C, in doped montmorillonite occurs above 70 degrees C. The conductivity activation energy is 0.27 eV. (c) 2005 Elsevier B.V.
