Abstract:

Orthotantalates of lanthanum, samarium, and europium were synthesized for the first time. Differential thermal analysis of the oxide mixture La203 Ta205 11 was carried out. X-ray diffraction pictures of LaTa04, SmTa04, and EuTa04, powders were indexed Monoclinic structure z4 space group I-2. It was determined that the pycnometric densities of LaTa04, SmTa04, and EuTa04 at 20C are 7.9, 8.8, and 8.9 gsq cm respectively. Magnetic susceptibility was measured at 78.194 and 289K. LaTa04 is diamagnetic while SmTa04 and EuTa04 are paramagnetic. Author
