High Temperature Technology

Temperatures above 1.000 °C are difficult to endure for most metals for a long period. Here engineering ceramics play the important rule to withstand operating temperatures of 1.750 °C and more without any problems. A further advantage of the ceramic materials is the (ultra) high vacuum resistance even at the highest operating temperatures. In addition, high-performance ceramics show an excellent dimensional stability, a softening and/or material flow does not occur. Besides the shape stability of oxide ceramics they are also characterized by a high chemical resistance with a corresponding good oxidation resistance, making them ideal for use as crucibles in the field of high performance analytical devices. BCE company manufactures precision and high purity Al2O3 crucibles with a purity up to 99.95%.

By affixing inner or outer threads, it is also possible to realize temporary joints in high-temperature applications. The production of customized solutions is easily feasible – including: ground-in lid with and without holes or threads, partial metallization of crucibles for soldering with other materials is also realizable as adding an electrically conductive surface for measuring contacts, etc.
