改进的油浸法测量聚硅氧烷微球的折射率

Measuring the refractive index of polysiloxane microspheres using modified immersion method

在传统的油浸法基础上,引入透光率指标来判断粉体与浸液折射率的差异,测量了聚硅氧烷微球粉体的折射率.该方法将传统油浸法的适用范围扩展至超细粉体甚至纳米粉体的折射率测量.

Based on the traditional immersion method, light transmittance was introduced to get the difference of the refractive index between powder and immersion liquid, thus the refractive index of polysiloxane microspheres was measured using this modified immersion method. This method expanded the application fields of ti＇aditional immersion method into superfine powders and nano-powders.
