Preparation method for synthesizing zinc titanate with spinel structure based on chloride molten salt system
The invention discloses a preparation method for synthesizing zinc titanate with a spinel structure based on a chloride molten salt system. The preparation method is characterized in that ZnO and TiO2 are used as main raw materials, KCl or NaCl-KCl is used as a molten salt raw material, ZnO, TiO2 and KCl or NaCl-KCl are uniformly mixed according to a certain ratio, then the obtained mixture is maintained at a constant temperature for a certain time, and then cooling, filtering and drying are performed to obtain the zinc titanate Zn2TiO4 with the spinel structure. According to the invention, the raw materials which are cheap, non-toxic and harmless are adopted, an operation process is simple, requirements on equipment are not high, and preparation can be completed in a laboratory scale.
本发明公开一种基于氯化物熔盐体系合成尖晶石结构钛酸锌的制备方法，其特征在于，以ZnO和TiO2为主体原料，以KCl或NaCl‑KCl为熔盐原料，将ZnO和TiO2与KCl或NaCl‑KCl按一定比例进行混合均匀，然后在恒定温度下维持一定时间，之后再通过冷却过滤烘干，制备成具有尖晶石结构的钛酸锌Zn2TiO4。本发明采用了成本低廉、无毒无害的原料，操作过程简单、对设备要求不高，在实验室规模即可完成制备。
