The influence of milling technology on the crystallite size and granulometry of tricalcium aluminate

The article deals with the monitoring and evaluating of the length of the milling process on the crystallographic and granulometric properties of the cubic tricalcium aluminate. Tricalcium aluminate was prepared by solidstate reaction and subjected to milling in a dry and wet conditions of three laboratory mills. The evaluation of the influence of the milling technology on the crystallite size was carried out on the selected main three crystallographic planes. The calculation of the crystallite size was based on the full width of half maximum. Full width of half maximum has been calculated for all the above diffraction lines in the HighScore Plus program. All types of selected laboratory mills in both dry and wet conditions for all three crystallographic planes affect crystallite size of tricalcium aluminate. In terms of granulometry, the material was very effective and significantly refined. The problem arises with long grinding time, where the material tended to form agglomerates.
