The physico-mechanical, chemical and mineralogical characteristics of volcanic glass (perlite) from the Mariovo region (Macedonia) as well as the mineralogical changes that occur during its thermal treatment were investigated to demonstrate its utilization for industrial use.The native perlite was characterized by chemical analysis, X-ray powder diffraction (XRPD), infrared (IR) spectroscopy, thermal analysis (TGA/DTA), scanning electron microscopy (SEM-EDX), transmission electron microscopy (TEM), and ...

Improved materials are required for increasing the durability of sugar mills trash plates, considering their mechanical properties. The aim of this work was to obtain a gray cast iron, slightly alloyed with chromium, to raise the combined wear resistance. The gray alloy cast was proposed with 0,5% Cr and 0,1% Sn, with a high level of perlite, and the performance of its properties was compared with the other experimental alloys. Finally, it is demonstrated that the values of hardness and combined ...
