Abstract Up to now, the thermal expansion behavior of multiphase glass-ceramics cannot be predicted reliably because of the nescience about the formation of the type and concentration of crystalline phases. In the system BaO-SrO-ZnO-SiO2, recently a

Solid solutions with the composition Ba0.5Sr0.5Zn2Si2-xGexO7 and BaZn2Si2-xGexO7 were prepared with different values of x using a conventional mixed oxide route. Both compounds exhibit very different thermal expansion, which is due to the different c

X-ray-computed tomography with sub-micron resolution (nano-CT) is one of the most useful techniques to examine the 3D microstructure of materials down to voxel sizes 10 nm. However, since size and shape of samples have considerable influence on acqui

Replacing Ba2+ by Sr2+ stabilizes the high temperature phase and leads to zero or negative thermal expansion. Replacing Zn2+ by Mg2+ or Co2+, Ni2+, Mn2+, Cu2+ shifts the phase transition to higher temperatures and leads to high thermal expansion.

In order to identify suitable volume nucleation agents in glasses, heat treatments and subsequent traditional microscopic investigations are necessary. Those analyses are laborious and time-consuming. Therefore, often DSC methods are used to get info

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

Volume crystallization was achieved in diopside glasses by the introduction of silver into the glassy network. Subsequent thermal treatments lead to the formation of metallic silver nanoparticles within the glass. The latter particles trigger the for
