High pressure crystallography: from mineral physics to material sciences — •Leonid Dubrovinsky — BGI, Bayreuth University, Bayreuth, Germany

Modern science and technology rely on the fundamental knowledge of matter that is provided by crystallographic studies. About a decade ago, our group pioneered an approach to the SCXRD data collection and analysis for the products of chemical reactions in laser heated DACs. Since then we have designed and built new instrumentation to enable sophisticated in situ experiments in house and on synchrotron radiation facilities. Our efforts have pushed the range of static pressures achievable in a DAC up to 1 TPa and enabled single-crystal X-ray diffraction experiments at such extreme conditions. Structural studies at simultaneous high pressures of over ~200 GPa and temperatures of several thousand degrees have also become possible. This has led to remarkable findings in solid state physics, mineral physics, and chemistry at extreme conditions.We illustrate application of new methodology for simultaneous high-pressure and high-temperature single crystal diffraction studies using examples of investigations of chemical and phase relations in the halides, nitrides, and carbonates.

Keywords: pressure; temperature; crystal structures; halides; nitrides
