SIeve+ is a powerful phase identification and analysis program.It is designed to work intimately with all Powder Diffraction File (PDFTM) databases.The strongest feature of the program is the ability to use all the embedded data mining software within the databases that includes 65 different searches as filtered (i.e.sieved) results in the identification process.Most commercial software systems only use a small subset of the available filters in a PDFTM database.The use of a wide range of filters has a very practical consequence in that the user can search the appropriate chemistry and physical properties exhibited by the specimen,eliminating false positives,directly leading to more accurate results (Fawcett et.al.,2011).
