The annual meeting of crystal growers in Germany, Deutsche Kristallzüchtungstagung 2015, took place in Frankfurt/Main from 4th to 6th March 2015. The meeting was organised and carried out by the Physics Department of the Goethe-Universität Frankfurt, particularly by Cornelius Krellner, Franz Ritter, Wolf Aßmus and their team, supported by the the German Crystal Growth Assosiation (Deutsche Gesellschaft für Kristallwachstum und Kristallzüchtung e. V., DGKK). SciDre contributed to the meeting with a talk by Dr. Paul Sass "Optical floating zone crystal growth under high-pressure atmospheres – advantages and applications" in the Thusday session "Intermetallics and Oxides", and with an information desk dealing with our latest developments especially concerning the HKZ furnace system. Furthermore, we exhibited the high-pressure oxygen sintering furnace HSO and the gas purification system GRS. Many thanks to the organizing committee for arranging the event!
