Special Issue Information

Dear Colleagues,

In this Special Issue, we are focusing on recent progress in the broad field of geomaterials, an important class of materials both from a scientific and a technological perspective. Geomaterials have exhibited a long-standing interest to the scientific community due to their diverse fields of applications, from the construction industry to implications for processes in the Earth’s and planetary interiors.

The properties of geomaterials under varying pressure and temperature conditions currently lie at the center of scientific attention worldwide, as a means of mapping out the phase diagrams of these systems. Notably, over the last few decades, geomaterials have continuously inspired and fueled the search for novel energy-related materials, to be exploited in a variety of applications (e.g., battery, thermoelectrics, photovoltaics). The potential topics of this Special Issue include but are not limited to the following:

  • Complex structural–electronic properties and potential interplay;
  • Synthesis and characterization of georelevant materials and analogs;
  • Modeling of geomaterials;
  • Temperature and/or pressure effects;
  • Scale effects: from nano- to macroscale;
  • Advanced experimental and computational techniques and methods;

Relevant review articles are also welcome.

Slawsonite’s (SrAl2Si2O8) structure evolutions depending on temperature (27–1000 °C) have been studied by in situ single-crystal X-ray diffraction. The SrO7 polyhedron expands regularly with the temperature increase. Silicon and aluminum cations are ordered in tetrahedral sites of the studied slawsonite; no significant changes in their distribution as temperature increases were observed. Slawsonite demonstrates a relatively high volume thermal expansion (αV = 23 × 10−6 °C−1) with high anisotropy, typical for framework feldspar-related minerals and synthetic compounds. It was found that, contrary to previously published data, the crystal structure of slawsonite is stable in the studied temperature range and no phase transitions occur up to 1000 °C. The role of Ca and Ba substitution for Sr and Al/Si ordering on polymorphism of natural MAl2Si2O8 (M = Ca, Sr, Ba) is herein discussed. Full article
