Furnaces
We inherit several muffle furnaces (Nabertherm), tube furnaces (Eurotherm), graphite furnaces (Linn High Therm) and an induktion furnace from Linn High Therm.
Microscopes
The Stereo Polarisationesmicrosopes (SZX-9, Olympus; zoom factor: 57) gives the opportunity to examin crystalls under polarisied light. One of the microsope is with a camera adapter equipped offering the possibility to take pictures of crystalls. "Only" stereo Microskopes (SZ-40, Fa. Olympus und BX-51, Fa. Olympus) with zoom factor 40 are also present. The BX-51 inherits an heating table (TS1500; Linkham), allowing temperatures up tp 1500°C. With the help of this microscope it is possible to follow high temperature phase transition.
Thermal Analysis
Measurable Parameters and Properties:
Temperatures and enthalpies of phase transitions, glass transitions, crystallisation, melting, reaction behaviour and kinetics, thermal stability, oxidation stability. In addition STA-449C und beim STA-409CD change of mass during the reaction can be obtained. To identify atoms and molecule fragments, which are released to the gas phase during the reaction STA-409CD is used.
All measurements regarding the instrument are performed in air or helium atmosphere. Standard crucibles are made of zirconium dioxide, aluminium oxide or aluminum
We use following instruments:
- LOW-Temperature DSC-204 "Phoenix" (Netzsch)
Temperature Range: -150° bis 600°C
Dynamic Difference Calorimetry (DDC) - High-Temperature DSC-404 (Netzsch)
Temperature Range: room temperature up to 1400°C (aluminium oxide or aluminum crucibles only up to 600°C)
Dynamic Difference Calorimetry (DDC) -
High-Temperature STA-449C "Jupiter" (Netzsch)
Temperature Range: room temperature up to 1450°C (aluminium oxide or aluminum crucibles only up to 600°C)
Simultaneous Thermal Analysis (STA): Dynamic Difference Calorimetry (DDC) with Thermogravimetry (TG)
- High-Temperature STA-409CD with Skimmer Coupling to a Quadrupole Mass Spectrometer (Netzsch)
Temperature Range: room temperature up to 1200°C (aluminium oxide or aluminum crucibles only up to 600°C)
imultaneous Thermal Analysis (STA): Dynamic Difference Calorimetry (DDC) with Thermogravimetry (TG) and Skimmer Coupling to a Quadrupol Mass Spectrometer for the evaporation gas analysis (EGA)
