Custom ceramic synthesis (example of solid-phase process)

Weighing and mixing
Mixing is performed with a mortar, planetary ball-mill, SC mill, etc.
Calcination
Gases released during the reaction may damage the sample integrity, so this preliminary firing is performed to remove volatile materials.
Pelletization
The mixture is mechanically pressed into pellet form
Firing
Firing is performed with a muffle furnace or an atmosphere-controlled tubular furnace (max. 1500℃)
Pulverization and analysis
Pulverization is performed with a mortar or planetary ball-mill. Characterization is by x-ray diffraction, and composition ratio analysis by ICP.

2. Synthetic Procedure Studies

Continuous-flow Synthesis

Various conditions are investigated to establish a process for continuous-flow synthesis, allowing production of the target compound from gram-scale to kilogram-scale.

Between the microreactor and the CSTR, reaction times from a few milliseconds to several hours can be accommodated. If necessary, batch synthesis steps may also be integrated into the process.
