Scientific Aspects of the Development and the Application of Ceramic Materials and Structural Components
Ever increasing attention to structural ceramics and their practical application can be attributed to the possibility of obtaining basically new technico-economical characteristics. However, ceramics as structural materials have been studied very little. While extensive and in-depth study in the field of design and manufacture of metallic structures has been carried out and hundreds of thousands of scientific papers have been published on the subject, investigations of load bearing ceramic structures are at the very beginning. At present designers lack practical experience in designing ceramic load bearing structures and basic data are often missing for reliable performance analysis. This is due to the fact that ceramics have been used as a refractory or building material for thousands of years and all research work has been done with that end in view. A specific feature of ceramics as a structural material lies in the fact that the ceramic components have to be made at once as a whole. So far it has been practically impossible to produce them by welding or deformation of a semi-finished piece. They cannot be joined by bolts, screws or rivets etc, which is a common practice when assembling metallic structures.
