Abstract

Using the lithium carbonate and bismuth oxide as additives for restricting the grain growth,the transparent potassium sodium niobate(K0.48-0.5xNa0.52-0.5xLixNb1-xBixO3,x=0.04-0.15) ceramics were sintered in atmosphere.The effect of additive content and sintering conditions on the transparency,electric-optic coefficient,crystalline structure and micro-morphology were investigated.The electro-optical coefficient of the KNN(x=0.09) ceramics with thickness of 0.5mm was found to be 6.06×1011m/V.
