Synthesis
 

The company GERO Hochtemperaturöfen has specialised in the construction of furnaces and crystal growth equipment for 30 years.

Both company founders come from the crystal growth laboratory of the Max-Planck Institute für Festkörperforschung in Stuttgart and have therefore concentrated on the growth of crystals and growth systems from the outset.

Our crystal growth systems are characterised by precise mechanical assemblies, with optimum balancing of turning parts, exactly defined temperature distribution including optimum gradients and precisely functioning control and monitoring assemblies.

We have also manufactured systems for the growth of II-VI materials, metals and alloys, optical monocrystals such as fluorides using the Bridgman, Stockbarger , flux, zone melting, chemical transport and sublimation method.

Over the years so many crystal growth machines have been built that we can draw on a large range of subassemblies, which can be put together as required.

Furnaces and Plants for Crystal Growth

tube furnace

Single zone universal tube furnace

Single and multi-zone tube furnace for annealing and synthesis.

Single zone universal tube furnace for working at specific angles and heights for annealing and direct synthesis

Split furnaces

Sublimation furnace

Split furnaces with two heating zones for synthesis,
each zone can be opened separately.

Sublimation furnace for sublimation of materials
for the purposes of material purification.

Bridgman equipment

Bridgman Plant

Bridgman equipment for suspended ampoules.
The ampoules are suspended on a special low-vibration drive system and feed into the furnace. Control cabinet with 6 regulated zones and touch panel operation of the motor controller.

Bridgman Plant with three zone split furnace and upright tubes and sample holder shaft within ceramic tube for operation under protective gas. The drive system is mounted underneath.

Crystal growth device

Bridgman furnace

Subassembly “Crystal growth device” can be mounted either below or above the furnace. Subassembly “Crystal growth device” can be fitted to every GERO furnace frame.
