The right solution for every requirement

Products made of oxide ceramics for sample preparation and material analysis in laboratories

DEGUSSIT AL23 oxide ceramic crucibles and combustion trays are used for high-temperature analysis of materials in industrial and academic laboratories. Kyocera offers a wide range of standardised sizes for ceramic crucibles, combustion boats and annealing trays which can be found in our online shop and in the standard product catalogue in our download section. If you are looking for special shape ceramic laboratory utensils, just send us an enquiry with your part drawing.

The high purity of our alumina ensures chemical stability and chemical inertia at high temperatures together with high dimensional stability. Our high-pressure pressing method ensures the homogeneous microstructure and accuracy of shape of these ceramic laboratory ware. The dense sintered surface of DEGUSSIT oxide ceramics is extremely resistant to highly aggressive metal or glass melts. Our DEGUSSIT AL23 material is suitable for ultra-high vacuum applications thanks to its no porosity structure so it can be used in wide spectrum of research environments. The low SiO2 content in DEGUSSIT materials helps to achieve the widely recognized and impressive corrosion resistance, significantly extending the service life of our ceramic crucibles and laboratory trays. In cooperation with our customers, we can adapt the dimensions and geometries of the parts to their specific process requirements.
