Material properties of DEGUSSIT oxide ceramics
Products made of DEGUSSIT oxide ceramics have been specially developed for use at high temperatures.
The strength, and thus the corrosion resistance, is determined by the chemical resistance of the grain boundary chamfers of the material structure. For optimum results, we therefore use high-purity alumina while reducing the use of by-products, particularly silicon oxide (SiO2), which lead to reduced corrosion resistance.
Finest selection of materials with high purity
For our tubes made of technical ceramics, we attach great importance to high purity in the materials used and select them according to the strictest criteria. Only in this way can we process the homogeneously formed microstructure with the most excellent care and under permanent controls to produce a ceramic tube that promises our customers and their applications special corrosion resistance and the outstanding dimensional stability that has been known for decades from the development of ceramic materials by Kyocera.
Characteristic properties of DEGUSSIT ceramic tube
- Extreme resistance to heat
- High form stability
- Extraordinary corrosion resistance
- Wear resistance
- Resistance to high electrical voltage
- Measurement accuracy due to good thermal conductivity of the materials

Ceramic tubes for dilatometry
Sample holders made of DEGUSSIT AL23 or DEGUSSIT AL24 ensure the highest precision, reproducibility, and long-term stability even at highest temperatures.

Tubes made of advanced ceramics for thermogravimetry
The ceramic sample holder is connected to a microbalance that records mass changes precisely while the test sample is exposed to heat. DEGUSSIT AL23 ensures accurate measurements for this procedure.
