چکیده انگلیسی
Macroporous barium strontium titanate ceramics consisting of closed cells with an average size of approximately 10 μm and exhibiting porosities in the range of 65–80% were synthesized using particle-stabilized emulsions. These ceramics, after sintering at 1450 °C for 2 h, exhibited high crystallinity and a cubic perovskite structure. The synthesized high-porosity macroporous ceramics exhibited a significantly lower dielectric constant (~315, when the porosity was 80%) than fully dense ceramics. The dielectric loss of the ceramics increased slightly with an increase in porosity, yet remained less than 0.2%.
