纳米钛酸钡的制备与表征在无机化学实验教学中的应用探索
Exploration of the Preparation and Characterization of Nano Barium Titanate and Its Application in Inorganic Chemistry Laboratory Teaching
摘要
Abstract
To address the issues of long reaction time,difficult reaction control,multiple impurities,and uneven particle size in the traditional barium titanate preparation experiment using the sol-gel method,an improved experiment was conducted.By replacing the experimental solvent,introducing surfactants,and incorporating low-temperature heat treatment,the reaction time was significantly reduced,resulting in the production of highly pure and ultrafine barium titanate nanoparticles with an average particle size of less than 20 nm.This improved experiment is suitable for undergraduate-level inorganic chemistry laboratory teaching in the first year.关键词
