Composite proton-conducting materials xCs6H (HSO4) 3 (H2PO4) 4+ (1 - x) AlPO4 were obtained in the composition range (x = 0.9–0.7). The methods of x-ray phase analysis, impedance spectroscopy, electron scanning microscopy studied their physicochemical and transport properties.

Densification of a precursor mixture of powders followed by drying to remove the excess of water is a necessary stage before the high temperature sintering to produce a ceramic piece. In the case of conventional red ceramics the influence of the density established during this stage has received limited attention in terms of the final product proprieties. Therefore, this work has for objective to evaluate the influence of the dry bulk density on the fired properties of red ceramics elaborated with the mixture of clays, argillite and grog. Cylindrical specimens were prepared with two different ranges of dry bulk density, 1.95-2.09 g/cm3 and 2.15-2.28 g/cm3. Specimens were fired at 1050°C in a laboratory furnace. The evaluated properties were: water absorption, diametral shrinkage and compressive strength. Microstructure of the fired ceramics was evaluated by electron scanning microscopy. Results showed that dry bulk density exercises a strong influence on the fired properties.

Abstract The presented work provides the results of the abrasive wear resistance tests performed on Co-Cr-Mo and Co-Cr-Mo-W alloys with the use of the Miller’s apparatus. The analyzed alloys underwent microstructure observations as well as hardness measurements, and the abraded surfaces of the examined materials were observed by means of electron scanning microscopy. The performed examinations made it possible to state that the Co-Cr alloys characterized in a high hardness, whereas the changes in the mass decrement were minimal, which proved a high abrasive wear resistance.
