Thermal, mechanical structural, and optical properties of the 80TeO2-xZnO-(20-x)Na2O (TZN) system were investigated. The structural study glasses showed that in TZN system, zinc had a coordination hence behavior change tellurite matrix as function concentration. Those results correlated to elastic glasses, like Young modulus, shear Poisson ratio, thermal with index stability crystallization ref...

We use classical molecular dynamics simulations to study the dynamics of sodium atoms in amorphous Na2O-4SiO2. We find that the sodium trajectories form a well connected network of pockets and channels. Inside these channels the motion of the atoms is not cooperative but rather given by independent thermally activated hops of individual atoms between the pockets. By determining the probability ...

Geopolymers can improve environmental protection and are therefore considered a 21st-century material that requires special attention. The main objective of this study was to examine the utilization fly ash deposited on heap as potential raw for geopolymerization process. In work, flexural compressive strengths, well water absorption geopolymers, were evaluated based alkaline activator properti...
