Summary The effects of Bi 2 O 3 addition on the phase composition, microstructure and optical properties of ZnO–SnO 2 ceramics were investigated. Starting powders of ZnO and SnO 2 were mixed in the molar ratio 2:1. After adding Bi 2 O 3 (1.0 mol.%) this mixture was mechanically activated for 10 min in a planetary ball mill, uniaxially pressed and sintered at 1300°C for 2 h. Far‐infrared reflection spectra were measured (100–1000 cm –1 ). To investigate the occurred differences in FTIR spectra, the Bi 2 O 3 ‐doped sample was examined more carefully with a Perkin–Elmer FTIR spectrometer (Perkin Elmer, Waltham, MA, USA) connected with a Perkin–Elmer FTIR microscope and itemized points of interest were also studied with SEM‐EDS.
