Study on the mechanical strength of primary carbonate tablets

The mechanical strength of three carbonate tablets constructed by uniaxial compaction is evaluated using a simple tester, specially designed, as a comparative method, to classify and establish correlations between the measured resistance and the physical and flow properties of each carbonate. The net compression work required to construct the tablets is also compared with the strength of the samples in order to relate it to powder's ability to convert the force applied into effective solid–solid bonds.

Graphical AbstractIt is perceivable that granules need a certain mechanical resistance to tolerate the stress during storage and transport processing. In this research, a correlation between the mechanical strength, determined by a comparative method particularly appropriate, and the net compression work involved, indicates that the compacts made with calcium carbonate CA present a higher resistance in comparison with other carbonates (MG and RE) under similar conditions according to the experimental results.Figure optionsDownload full-size imageDownload as PowerPoint slide
