The analysis using Xpert HighScore Software showed that the sample is a mixture of three phases, how can I know which one are the greatest percentage in the sample?
The percentage of each phase can be determined by a method called Rietveld Refinement. It is possible to do it in HighScore, but you would need to download the CIF files of the materials you want to determine. HighScore can use many databases to identify phases, but they don't have CIF files and it means that they don't have information about atoms in the structure. I can help you with it, I can access HighScore and guide you how to do it.
To determine the highest percentage in a sample consisting of three phases, you would first need to know the percentages of each phase in the sample. Once you have these percentages, you can compare them to find the highest one.
