Phase analysis and microwave dielectric properties of BaO-Nd 2 O 3 -5TiO 2 composite ceramics using variable size TiO 2 reagents

Snashall, Amanda; Noren, Lasse; Liu, Yun; Yamashita, Toru; Brink, Frank; Withers, Raymond


There are significant inconsistencies in published literature surrounding the phase analysis and physical properties of ceramics with the nominal composition BaO-Nd2O3-5TiO2 (BNT125). A careful phase analysis investigation of BNT125 ceramics using variable size TiO2 reagents was therefore undertaken using XRD, FESEM and EPMA with corresponding dielectric properties characterised over 2-3 GHz. Three distinct phases were consistently formed: Ba6-3xNd8+2xTi18O54 (x ∼ 0.67), Ba2Ti9O20 and TiO2. The...[Show more]
