科研成果在无机化学实验中的运用

Application of Scientific Research Knowledge in Inorganic Chemistry Experiments

通过对一科研项目成果进行转化,设计出了一个无机化学实验:利用燃烧法制备氯硼酸锶铽荧光粉,学生通过控制炉温、尿素用量、硼酸用量、Tb^(3+)浓度等条件制备颗粒细小、发光性能良好的荧光粉,实验综合性强,对于提高学生无机制备实验能力具有很好的教学效果。通过将科研成果运用到无机化学实验改革中,拓展无机化学实验内容,培养学生的科研意识和环保意识,是进一步深化无机化学实验改革的必然趋势和发展方向。

An inorganic chemistry experiment is designed by the conversion of a scientific research. The experiment described preparation of Sr2B5O9 Cl： Tb^3＋ by combustion synthesis. Students were required to obtain small phosphor with good luminescence by controlling the temperature, amount of urea, dosage of boric acid and Tb^3＋ concentration. The high comprehensive experiment can be beneficial to the improvement of students＇ preparation ability in inorganic chemistry experiment. It is an inevitable trend and developmental direction for further deepening reform of inorganic chemistry experiments containing the application of scientific research in reform of inorganic chemistry experiments, development the contents of inorganic chemistry experiments and training scientific research and environmental consciousness of students.
