| Due to high production costs, easy to introduce the impurities, and low productivity,it has not been able to achieve industrial production. In order to overcome these shortcomings, and to obtained AB electronic ceramic powders to meet the requirements of the development of modern technology in efficient, simple, low-cost, high-quality method. this paper will mix A and B at room temperature , and then calcined at lower temperature Methods, formative AB won the molar ratio of the system is about 1.0, particle size distribution and uniform particle size in the 15 ~ 20 nm nano-powders of AB. Not only overcome the liquid phase method in aqueous solution preparation of easy introduction of impurities, defects and low production efficiency, the calcination temperature of solid-phase method than the traditional low of about 400-600 ◦ C. This method not been reported in the literature. Using XRD, SEM, TEM, FT-IR of the products were characterized and used TG-DTA of the former body of the calcination reaction was analyzed |
