The effect of zinc oxide and calcium fluoride on the clinkering of alite-sulfoaluminate (ACSA) materials has been studied by laboratory X-ray powder diffraction (EDX) and scanning electron microscopy (SEM). ACSA clinkers without the addition of calcium fluoride did not contained C3S, and showed CaOfree (5·0(1) wt%). However, by adding 0·25 wt% of calcium fluoride, the obtained clinker did not contain free lime and showed C3S (20·0(2) wt%). The suitable clinkering temperature has been proved to be 1300°C, in order to avoid C4A3S decomposition. The optimum amount of zinc oxide was found to be 1·0 wt% as the maximum percentage of C3S was formed. An ACSA clinker prepared at 1300°C with 1·0 wt% of zinc oxide and 1·0 wt% of calcium fluoride contained 34·2(2) wt% of C3S coexisting with 15·2(2) wt% of C4A3S, determined by Rietveld methodology, including amorphous content. SEM-EDX results have been statistically analysed and particles have been univocally identified. It has been proved that zinc oxide is preferentially placed in C3S.

Cubic nanoparticles are referred to as the best shaped particles for magnetic hyperthermia applications. In this work, the best set of values for obtaining optimized shape and size of magnetic particles (namely: reagents quantities and proportions, type of solvents, temperature, etc.) is determined. A full industrial implementation study is also performed, including production system design and technical and economic viability.
