Dc bias voltage effects on the giant dielectric properties of CaCu3Ti4O12 ceramics prepared by polymer pyrolysis solution method

Thanin Putjuso; Ekaphan Swatsithang; Teerapon Yamwong; Sunan Nonglak; Chanwit Boonchuay (Rajamangala University Of Technology Rattanakosin, 2013)

This research is prepared the CCTO powders by using the polymerpyrolysis solution method. Microstructure and phase composition were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Study the ...
Magnetic Properties of Copper and Manganese Co-doped Cobalt Ferrites Nanoparticles by Sol-Gel Method

Anuchit Hunyek; Thanin Putjuso (Rajamangala University Of Technology Rattanakosin, 2015)

Cobalt ferrite nanoparticles with norminal formula of Co1-(x+y)CuxMnyFe2O4 have been synthesized by sol -gel method. The cobalt ion are replaced by copper and manganese ion (x + y = 0.08). Phase identification was ...
