Abstract

In some applications mirrors and support structures from the zero expansion glass ceramic material ZERODUR^(R) have to endure mechanical loads, e.g. rocket launches or controlled deformations for optical image correction. Like for other glassy materials the strength of glass ceramics is dominated by its surface condition. Similar to other glass ceramics ZERODUR^(R) has higher strengths than glasses for comparable surface conditions. For the design of ZERODUR^(R) parts well known rules of thumb for its strength are not sufficient in any case. So new information and data with enlarged sample sets and hence better statistics have been collected to improve the understanding of its behavior under mechanical loads. Finally an outlook is given on the application of ZERODUR^(R) in ambitious current and future space projects.
