摘要: Abstract Sodium niobate – NN (NaNbO 3 ) powders were synthesized by hydrothermal process to be used as template particles in the fabrication of textured lead free piezoelectric ceramics. hexaniobate–Na 8 Nb 6 O 19 ⋅13H 2 with rod-like morphology at 120 °C. Particles needle-like and Na (Nb )(H O) phase started form temperatures 130 °C above. Synthesis 150 °C yields totally consisting entirely phase. niobate–NaNbO cubic 160 °C Rod-like was retained even after annealing 400 °C for 1 h. A preliminary study also done integrate these anisometric preparation potassium sodium (KNN) fibers.
