The sintering process of the KSr2Nb5O15 ceramic doped with different amounts of CuO was investigated in this research. It was found that CuO is effective as promoter of the densification process of the KSN ceramic. The developed microstructures were different due to the amount of CuO and secondary phases were observed in the microstructures. However, the results of X - ray diffraction showed that only the tetragonal tungsten bronze (TTB) structure was identified in all the investigated ceramic systems. The thermal behavior of CuO and also of the CuO - KSN phase mixture was investigated by thermal analysis.1704-1709porTTB niobatesthermal analysisliquid phase sinteringArtigo10.1590/S0100-40422009000700004S0100-40422009000700004WOS:000271424900004Acesso abertoS0100-40422009000700004.pdf49219483748200650000-0002-7772-2701
