摘要：
The sintering behaviors and microstructures of reaction-sintered Sr0.4Ba0.6Nb2O6 (RSBN40) using mixture of SrNb2O6 and BaNb2O6 as the starting powders were compared with that of normal sintered Sr0.4Ba0.6Nb2O6 (SBN40) with single-phase Sr0.4Ba0.6Nb2O6 powders as starting powders. The experimental results show that the densification rate of SBN40 is faster than that of RSBN40. Densities of samples SBN40 and RSBN40 reach the maximum, 5.21 and 5.27g(.)cm(-3) at 1250 and 1300degreesC, respectively. In addition, abnormal grain growth occurs more easily in sample SBN40 than in sample RSBN40 at the sintering temperatures above 1300degreesC.
