Impact mechanism of gel’s alkali circumstance on the morphologies and electrical properties of Ba0.80Sr0.20TiO3 ceramics

1. Gelation and pyroreaction processes for Ba0.8Sr0.2TiO3 nanopowder were studied. 2. Pyroreaction induced the nanopowder from cubic to tetragonal phase transition. 3. Ceramics were prepared by Pechini sol-gel method with different pH values. 4. Interrelationship of ceramics morphology and electrical properties was shown.
