The structural and ferroelectric characteristics of SrBi 2 (Nb 1Γx W x ) 2 O 9 (x ΒΌ 0-0.12) ferroelectric ceramics were investigated. SrBi 2 (Nb 1Γx W x ) 2 O 9 ceramics consisted of a single-phase layered perovskite structure when x was less than 0.06. Uniform microstructure and grain size reductio
Ceramic compositions of strontium bismuth tantalate (SBT) [Sr 1Γx Bi 2+2x/3 Ta 2 O 9 ] with x = 0.0, 0.15, 0.30, 0.45 prepared from a sol-gel process have been studied. Stoichiometric and non-stoichiometric phases stable within the series have been investigated for their structural, dielectric, ferr
