Abstract

A combination of digestion and further low temperature calcination to crystallize the product is employed to prepare BaNb2O6 ceramics. Freshly prepared niobium hydroxide gel is mixed with barium hydroxide thoroughly and allowed to react at 100°C under refluxing and stirring conditions for 6-12 h. The X-ray amorphous product so formed is heated at 500°C to form crystalline BaNb2O6. This is the lowest temperature so far reported for the formation of BaNb2O6. Transmission electron microscope (TEM) investigations revealed that the average particle size is 50 nm for the calcined powders. The room temperature dielectric constant at 1 kHz is found to be 600. The ferroelectric hysteresis loop parameters of these samples were also studied.
