The particle size of reduced iron powder was examined by microscope

Method for measuring particle size of powder by optical microscope

As the reflected light optical microscope only can measure the particle size is greater than 5 micron particulate matter, therefore granularity analysis generally work with transmission light microscope In order to calculate grain size, on the microscope eyepiece with a microscopic scale, scale should be calibrated in advance before using there are three kinds of commonly used to analyze the microscopic scale: (1) linear scale with reticle;(2) network microscale;(3) Pattern microscopic scale.

The principle and advantages and disadvantages of measuring powder particle size by microscope

Microscope method of measuring the performance of the particle size, the particle size of projection symmetry good spherical particles (such as atomized powder) or cube particles can be directly calculated at diameter or length But for irregular non spherical particles, cannot be used directly computing method, must consider the different methods of said microscope method operation is the chief drawback of complicated and arduous.
