“…The thoria samples employed in this work were produced by the oxalate precipitation route [9]. The certification was done in frame of a national inter-laboratory comparison experiment (ILCE) conducted by the Department of Atomic Energy (DAE), India, where 13 laboratories of DAE participated [10].…”

“…For certification of impurities, F-test was conducted on the data from the different techniques employed. Thoria powder was prepared based on the method used by Allred et al [14] through the oxalate precipitation route. Though the RSD values is quite large for some of the elements in Table 1, they are within expectable limit for material to be used in nuclear industry and follow the statistical evaluation criteria of international atomic energy agency (IAEA) for inter-comparison experiments [15].…”

“…The equivalent BET particle diameter was calculated according to the equation given in Ref. 39 assuming the powder particles were spherical or cubic in shape. Scanning electron microscope images and energy dispersive X-ray analyses (EDX) were recorded with a Philips XL30 ESEM (Environmental Scanning Electron Microscope) and an attached energy dispersive Xray spectrometer from Edax.…”

DTA, XRD and sintering investigations of the system BaSnO 3 -BaGeO 3 , prepared by a mixed-oxide method, are described herein. The melting temperature of this system is about 1270 ± 5 • C. We find a partial solubility of BaGeO 3 into BaSnO 3 of the order of 6-7 mol%. Up to 50 mol% BaGeO 3 , the calcined powders (1150 • C) as well as the once-sintered samples consist of BaSnO 3 and orthorhombic BaGeO 3 at room temperature. A gradual appearance of hexagonal BaGeO 3 can be observed in calcined powders and once-sintered ceramics with a BaGeO 3 content above 50 mol%. After sintering at ≥1200 • C for more than 1 h all ceramic bodies consist of BaSnO 3 and orthorhombic BaGeO 3 . The addition of BaGeO 3 leads to a considerable reduction of the sintering temperature and to a strong densification. Sintering at 1180 • C for 10 h and an addition of only 1 mol% BaGeO 3 leads to dense ceramic bodies with cubic-like grains.
