My research focuses on the physicochemical processes in silicate glasses, melts, and magmas, using high-temperature and high-pressure experiments, synchrotron X-ray facilities, and various analytical methods.

    Crystallization in natural melts: nanoscale approach to volcanic eruptions and unconventional ways to derive melt viscosity

    Understanding the mechanisms of magma fragmentation and the explosive behavior of volcanoes is one of the key challenges in volcanology and eruption forecasting. Central to this is magma viscosity, which significantly influences fragmentation and the likelihood of explosive eruptions. However, recent evidence suggests that the chemical and temperature dependence of magma viscosity is not yet fully understood, impacting the accuracy of numerical models used for probabilistic eruption predictions. Extending insights from glass-ceramics studies, it has been shown that nanocrystal formation can significantly alter magma viscosity measurements. This contribution shares a multipronged analytical and experimental approach using thermal analysis techniques (standard and flash DSC, TMA), Raman and Brillouin spectroscopies, and transmission electron microscopy. These methods enable the derivation of the glass transition temperature and fragility of glass-forming melts prone to nanocrystallization. Additionally, this contribution will highlight the need for further research, particularly on the dependence of melt viscosity on structurally bonded water. We will discuss how a multidisciplinary effort, including in situ observations, can lead to a comprehensive understanding of nanocrystal formation processes. This effort will highlight their impact not only on magma viscosity and volcanic eruptions but also on fundamental studies of glass-forming melts.

    I received my PhD degree, speciality Materials Science and Engineering, from the University of Grenoble (France) in 2004. After three years of experience in different laboratories in France, I joined the CNRS at the Groupe de Physique des Matériaux (GPM) laboratory in Rouen (France) in 2007 and then the Conditions Extrêmes Matériaux : Haute Température et Irradiation (CEMHTI) laboratory in Orléans (France) where I still am since 2013. I focus my work on microstructural characterization from the nanometer to the atomic scale by transmission electron microscopy (TEM) and associated spectroscopies (EDS/EELS). Currently I am developing a TEM in-situ temperature approach to characterize the crystallization mechanisms occurring in oxide glasses.

    In-situ temperature experiments in a Transmission Electron Microscope (TEM) : insights into crystallization mechanisms occurring in glasses.

    Glass-ceramics are materials obtained from the controlled crystallization of glass. The term crystallization here encompasses nucleation and growth of one or more crystalline phases, that is to say the establishment of a long-distance periodicity, in an amorphous matrix. In order to control the innovative properties of glass-ceramics, it is essential to tailor their microstructure, namely the composition and size of the vitreous domains as well as the nature and geometric arrangement of the crystalline phases.1 For this purpose, it is necessary to master the crystallization mechanisms and therefore to understand them well. A set of techniques already make it possible to monitor these phenomena in situ versus temperature, such as XRD, Raman spectroscopy or DSC for example. Recently, we are seeking to develop a new approach which is in situ temperature experiments in a Transmission Electron Microscope (TEM). The advantages of this approach are to be able to visualize directly the different steps such as the possible modification of the glass, the nucleation then the growth of the crystals.2 It is also possible to rapidly cool the material during the experiment in order to analyse the microstructure in more detail by obtaining chemical and structural information at key points.

     Email: thomas.hoeche@imws.fraunhofer.de

    Thomas Höche's research interests concern nanostructuring of inorganic materials as well as their characterisation using cutting-edge techniques of microstructure diagnostics. Special emphasis is laid on the development of novel, laser-based approaches to specimen preparation, the fabrication of polymer-based microoptics, and the accelerated development of glasses and glass ceramics fostered by accompanying micro- and nanostructure characterization. Having a background in physics, he is heading the department Optical Materials and Technologies at Fraunhofer IMWS, has authored ca. 230 peer-reviewed papers, holds more than 65 patents.

    Microstructure of Glasses and Glass Ceramics – What Can We Expect From Advanced Methods?

    The microstructure of glasses and glass ceramics can be extremely complex as is the relation of the microstructure to macroscopic properties. 
    Cutting edge tools for the characterisation of the microstructure can help assessing their chemistry, valency, coordination, and 3D element distribution.
    Using various compositions, it will be exemplified how the development of materials can be accelerated using new methodologies that have only recently have become available.

    He received his PhD from Nagaoka University of Technology in 2004. He then worked as a researcher at Mitsubishi Electric Corporation, and since 2007, he has been engaged in research on glass ceramics as an assistant professor at Nagaoka University of Technology. He was promoted to Associate Professor in 2014 and to Professor in 2023. He is working on the creation of ionic conductors and all-solid-state batteries with oxide glasses and glass-ceramics.

    Sodium ion conductive glass-ceramics processed by laser-based powder bed fusion technology

    Oxide all-solid-state sodium batteries (Na-ASSB) are expected to be one of the candidates for next-generation secondary batteries because they do not depend on scarce resources and are composed of non-flammable materials. Na3Zr2Si2PO12 (NZSP) is well known as a sodium superionic conductor (NASICON) structure crystal. By tuning the sintering process, NZSP exhibits superior sodium ion conductivity of 1 mScm-1 at room temperature. However, improving the ionic conductivity of NZSP by the usual solid-state reaction process requires long heat treatment, and the grain boundary resistance governs its ionic conductivity. Therefore, it is important to synthesize solid electrolytes that combine densification and ionic conductivity. This study proposes laser processing to prepare NZSP film without conventional sintering. Laser light enables the formation of a melt-pool, and solidification will be achieved. Morphology, crystallinity, and ionic conduction in the laser-induced layer were investigated.
    NZSP was prepared using the sol-gel process and conventional heat treatment. 5wt% of acetylene black was added to NZSP as a laser light absorbent. A nano-second pulse laser with a 1064nm wavelength was irradiated on the surface of compact powder. 
    Cross-sectional SEM image of laser-irradiated 5wt%AB added NZSP via scanning electron microscope show that the depth of 20 m from the surface is found to be melt-solidified. Powder X-ray diffraction and differential thermal analysis showed that the melt-solidified region was found to be amorphous. When the amorphous NZSP was heat-treated again at 1000°C for 10h, the NZSP recrystallized while retaining its high-density morphology. Impedance spectra of NZSP immediately after laser irradiation and after recrystallization shows that the crystalline NZSP shows higher ionic conductivity than the amorphous state. It is also noteworthy that it is possible to separate self-supporting NZSP sheets from the powder compact, as is done with 3D printing technology via the powder bed fusion process.

    Oriented Surface Crystallization in Glasses

    Up to now, oriented surface crystallization phenomena are discussed controversially, and related studies are restricted to few glasses. For silicate glasses we found a good correlation between the calculated surface energy of crystal faces and oriented surface nucleation. Surface energies were estimated assuming that crystal surfaces resemble minimum energy crack paths along the given crystal plane. This concept was successfully applied at the Institute of Physics of Rennes in calculating fracture surface energies of glasses. Several oriented nucleation phenomena can be herby explained assuming that high energy crystal surfaces tend to be wetted by the melt. This would minimize the total interfacial energy of the nucleus. Furthermore, we will discuss the evolution of the microstructure and its effect on the preferred crystal orientation.
