Thermoanalytical methods are widely
used in all fields of materials characterization. Especially
in the areas of ceramics and glasses, thermal methods such as
pushrod dilatometry yield crucial information for the production
of the materials and for their later application.
Pushrod dilatometry is a method for determination
of dimensional chang-es versus temperature or time when the sample
undergoes a controlled temperature program. The specific materials
properties gathered from this, are as follows:
Analysis of
Thermal expansion
Coefficient of Thermal Expansion
Expansivity
Volumetric expansion
Density change
Sintering temperature and shrinkage steps
Glass transition temperatures
Softening points
Phase transitions
Influence of additives
The
newly developed DIL 402 PC is especially tailored to the needs
of the glass and ceramic
industries. High resolution and stability, wide measurement range,
robust and compact design are only some of the advantages of
the new, cost-effective system. The system can be equipped with
two furnaces, allowing measurements to be carried out from room
temperature up to 1200°C or even up to 1600°C.
The system works according to
nearly all national or international standards (e.g. DIN 51045
or ASTM 831).
NETZSCH offers
precision thermal analysis instruments including advanced dilatometers (with
a new basic R&D/QC dilatometer),
classical DSC & TGA (with
a new economical DSC), high temperature DSC
to 1650°C for specific heat, very high temperature STA
(TGA-DSC/DTA) to 2400°C (featuring the new STA
409-PC Luxx®), thermal
/ evolved gas analysis with fully-integrated FTIR & MS, plus
high resolution TMA and DMA.
We also feature leading technology for thermal conductivity and diffusivity measurement
as well as refractories testing including HMOR, CIC, and RUL.
