High-performance ceramics in high-temperature technology

Components made of DEGUSSIT high-performance ceramics for high-temperature technology

Tubes made of densely-sintered high-quality Al2O3 ceramics are tried-and-tested components in plant used in the glass and metal manufacturing and processing industry, in industrial furnace manufacturing and in the chemical base-materials industry. Such systems operate in conditions that place exceptionally high demands on the dimensional stability of the ceramics in a corrosive environment as well as at extreme temperatures.

Among the densely-sintered ceramic types, the material and product behaviour of DEGUSSIT AL23 provides the optimum combination of these three properties. The dimensional stability of DEGUSSIT AL23 can be surpassed only by DEGUSSIT AL24, which was especially developed for high-temperature applications.

At temperatures exceeding 1500°C, DEGUSSIT AL23 and DEGUSSIT AL24 materials truly prove their exceptional qualities!
