Affect of Temperature Small Region Mutations on Bi_4Ti_3O_(12) Nanomaterial Morphology and Structure

为了研究在温度小区域突变的环境下铁电纳米材料结构和形貌变化。在NaOH或KOH为矿化剂的条件下,设计温度小区域突变环境设计试验,研究矿化剂催化作用下,温度小区域突变反应环境下Bi_4Ti_3O_(12)纳米片的水热反应机理,得到了温度线区域突变因素对Bi_4Ti_3O_(12)纳米片空心球结构和形貌的影响曲线。得到试验结论为:随着温度小区域突变程度的加大,Bi_4Ti_3O_(12)纳米材料的溶解速率和成核生长速率增强,随着温度小区域突变频率的增加,Bi_4Ti_3O_(12)纳米片空心球状物表面逐渐形成纳米片状结构,纳米片不断扩大,实心球从里到外不断熟化,产生纳米片构成的壳层空心球状结构。

In order to study the temperature under the environment of small region mutations ferroelectric nanometer material structure and morphology changes. In NaOH or KOH as the mineralizer, under the condition of small area design temperature mutations environment design test, the study of mineralizer catalysis, the small region mutation reaction temperature environment Bi4Ti3O12 nanoparticles the water thermal response mechanism, the factors on temperature line area mutations Bi4Ti3O12 nanoparticles affect the structure and morphology of hollow ball curve. Test conclusion is： with small area mutation degree of increasing temperature, Bi4Ti3O12 dissolution of nanomaterials growth rate and nucleation rate increase, with the increase of temperature of small area mutation frequency, Bi4Ti3O12 piece of hollow spherical surfaces gradually formed nano flake structure, nano expanding, medicine balls from inside to outside cure, constantly produce nano shell consisting of hollow spheres.
