Abstract:
     A process for preparing high-purity strontium titanate nanoparticles as dielectric material includes such steps as preparing high-purity water, preparing the gel of n-titanic acid, adding strontium source to the gel to synthesize the suspension of strontium titanate, washing, regulating the mole ratio of Sr to Ti, and drying. Its advantages are low cost, easy control and high activity of product.
