Densification of tetragonal tungsten-bronze (TTB) structured KBa 2 Nb 5 O 15 ceramics was studied as a function of extra K 2 CO 3 amounts (ฮด) ranging from 0 to 5 mol%. The lattice constant c-axis, which corresponds to the spontaneous polarization direction for TTB structure, was remarkably increased
