Autor: Erlebach, Andreas, Thieme, Christian, Müller, Carolin, Hoffmann, Stefan, Höche, Thomas, Rüssel, Christian, Sierka, Marek

Publikováno v: Phys. Chem. Chem. Phys., 2020,22, 18518-18525

Origin and composition dependence of the anisotropic thermomechanical properties are elucidated for Ba1-xSrxZn2Si2O7 (BZS) solid solutions. The high-temperature phase of BZS shows negative thermal expansion (NTE) along one crystallographic axis and h

Structure and crystallization of SiO2 and B2O3 doped lithium disilicate glasses from theory and experiment

Autor: Erlebach, Andreas, Thieme, Katrin, Sierka, Marek, Rüssel, Christian

Publikováno v: Phys. Chem. Chem. Phys., 2017,19, 25298-25308

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 combination of simulations at the density functional theory level and exp
