Phase stability determination of negative thermal expansion silicates by theory and experiment
Andreas Erlebach, Ghada Belhadj Hassine, Christian Thieme +3
Materials that exhibit zero thermal expansion have numerous applications, ranging from everyday ceramic hobs to telescope mirrors to devices in optics and micromechanics. These mat…
Thermomechanical properties of zero thermal expansion materials from theory and experiments
Andreas Erlebach, Christian Thieme, Carolin Müller +4
Origin and composition dependence of the anisotropic thermomechanical properties are elucidated for Ba1-xSrxZn2Si2O7 (BZS) solid solutions. The high-temperature phase of BZS shows…
Structure and crystallization of SiO2 and B2O3 doped lithium disilicate glasses from theory and experiment
Andreas Erlebach, Katrin Thieme, Marek Sierka +1
Solid solutions of SiO2 and B2O3 in Li2O 2SiO2 are synthesized and characterized for the first time. Their structure and crystallization mechanisms are investigated employing a com…
Structure evolution of nanoparticulate Fe2O3
Andreas Erlebach, Heinz-Dieter Kurland, Janet Grabow +2
The atomic structure and properties of nanoparticulate Fe2O3 are characterized starting from its smallest Fe2O3 building unit through (Fe2O3)n clusters to nanometer-sized Fe2O3 par…
