Abstract


Two sections was included in this dissertation, one was the preparation of electronic ceramic materials strontium titanate with hydrothermal synthesis method; the other was the preparation of copper nanopowder by reduction in aqueous solution. Strontium titanate has high dielectric constant and piezoelectric、 electrooptic properties, is an excellent ferroelectric materials. The copper powder is important material in industry, because it has many advantages: low resistivity、 high electromigration resistance and so on. It has many wide applications, such as the electronically conductive adhesives, ceramic materials, catalysts and electrode materials. The first section include the following several contents:（1）: Preparation of strontium titanate nano-fibres by hydrothermal method, the influence ofdifferent synthetic time、 temperature. （2）: The conditions was researched that the high-pressure hydrothermal method wassubstituted by normal-pressure hydrothermal method, it benefitted industrialization of strontium titanate. （3）: Ba0.6Sr0.4TiO3 was respectively prepared by high-pressure hydrothermal method andnormal-pressure hydrothermal method. The second section include the following several contents:（1）: Copper powder was synthesized by chemical reduction, and the influence of thedifferent concentrations of reactant to product was researched. （2）: Copper powder was synthesized by glycol as reducing agent, and the influence of thedifferent raw materials to product was researched.（3）: Copper powder was synthesized by ascorbic acid as reducing agent, the influence of dispersant to product was discussed, and the condition of washing the product was compared with glycol as reducing agent.
