Fabrication of sodium potassium niobate ceramics by two step sintering assisted molten salts synthesis

Fabrication of sodium potassium niobate ceramics by two step sintering assisted molten salts synthesis

Potassium sodium niobate (KNN) powders were synthesized by a molten salt synthesis. The pure phase KNN was achieved for a calcination temperature of 500 °C which is lower than the conventional technique by 400°C. The KNN ceramics were then fabricated by a two steps sintering technique. Effects of dw...
