Description

The Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences is the national centre for geosphere research. As a member of the Helmholtz Association of German Research Centres we are part of the largest scientific organization in Germany. With approximately 1,500 employees our key mission is to secure a profound understanding of the systems and processes of solid Earth, to develop strategies and options for action in addressing global change and its impacts on a regional level, to understand natural hazards and to minimize associated risks, to ensure the sustainable provision of energy and raw materials for a high-tech society and to evaluate the influence of human activity on system Earth.

To complement the Interface-Geochemistry team, we are looking for a PhD student (f_m_x) to carry out research with a focus on crystallization processes.

PhD Position (f_m_x) in Mineral Crystallization

Reference Number 7662

The aim of the PhD project is to improve our understanding on how various additives used in gypsum board formulations impact the kinetics and mechanisms of gypsum crystallization and the microstructure of the resulting gypsum matrix. The ultimate goal is to identify the reactions leading to a reduction in the gypsum quantity used in gypsum boards, while keeping the sustainable performance requirements.
 
The experimental PhD project will be carried out in our GFZ Mineral Synthesis Laboratories and this work will be complemented with training and experiments related to mechanical testing and scaling up of the experimental results to ‘real’ factory conditions. This latter part will be done in close collaboration with ETEX staff and in dedicated ETEX laboratory facilities.  
 
The successful candidate will become an integral part of the Interface Geochemistry section, work closely with other students and postdocs in the group and be registered in the PhD programme of the Freie Universität Berlin.

Your responsibilities
