Method for observing internal microtopography of spherical silicon dioxide micro powder particles

The invention discloses a method for observing the internal microstructure of spherical silicon dioxide micro-powder particles, which comprises the following steps: putting a proper amount of spherical silicon dioxide micro-powder into molten resin, putting the molten resin into a grinding tool cylinder, putting the grinding tool cylinder into a sample pressing machine, pressing the mixture into a columnar shape, taking out a columnar sample, and polishing the columnar sample on a polishing machine by using a polishing abrasive disc, and washing with water during polishing, drying the polished sample in a drying oven, observing the polished surface of the dried sample in a field emission scanning electron microscope, and clearly observing the low-light structure in the spherical silicon dioxide micro-powder particles. 本发明公开了一种观察球形二氧化硅微粉颗粒内部微观形貌的方法，将适量球形二氧化硅微粉放入熔化的树脂里面，放入磨具圆筒中，将磨具圆筒放在压样机里将混合物压制成柱状，将柱状样品取出后在抛光机上用抛光砂片进行抛光，抛光时用水冲洗，抛光好的样品放入烘箱内烘干，将烘干后的样品在场发射扫描电镜内观察其抛光面，可以清晰的观察到球形二氧化硅微粉颗粒内部的微光结构。
