DEGUSSIT oxide ceramics are also convincing when preparing samples for raw materials analysis and materials analysis. The use of pure raw materials and decades of experience ensure process safety in accordance with industrial standards for highest temperatures. The DEGUSSIT product range comprises a variety of annealing boxes, boats and crucibles in different geometries and materials used for annealing and melting processes. The dense surface of DEGUSSIT oxide ceramics is highly resistant to particularly aggressive melts. The low SiO₂ content of DEGUSSIT materials helps produce the widely recognised and impressive corrosion resistance significantly enhancing the service time of crucibles.
