Abstract

We report the influences of the sodium dodecyl-benzenesulfonate (SDBS), hydrothermal reaction temperature and time on the size of potassium sodium niobate (K,Na)NbO3 (KNN) template particles to determine the regularities of these changes. In the reaction with a small autoclave, when the quantity of SDBS reached 1.5 wt %, the width of the obtained platelike KNN-hydrate particles reached a maximum of 1.5 μm and the thickness was 0.15 μm, meaning that the aspect ratio was 10/1. To accommodate practical applications, a large autoclave was used in the following hydrothermal reaction. We found that the size of the platelike particles increased with improved reaction temperature and time. Particles 1.5 to 5 μm wide and 0.15 to 0.4 μm thick were prepared. After calcining these particles at 450 °C, platelike KNN template particles were obtained. Finally, tape-casting results showed that the platelike KNN templates have the (100) orientation.
