Measurement on Refraction of Crystal Powder
Abstract: Because of the special properties and applications Crystal powder in varieties of devices, scientists have studied the physical properties of the crystal powder, and got a lot of research results. They have a new understanding of crystal powder and have a effect of promoting the application of crystal powder. The error of directive measurement of powder refraction is big, and there are operating problems, etc. So most are not directly measured, but obtained by indirect methods.By means of measuring the refractive index of different concentrations of NaCl solution, and the refractive index changes according to the solution concentration; Use linear regression figure to determine its linear equations and calculate the refractive index of NaCl powder by extrapolation method. So the results of refractive index measurement has a certain reference value.
