Abstract

The spin casting technique has proved successful in the production of several raw blanks of the 8-m category. After the solution of start-up problems several castings could be successfully cooled down to room temperature. The quality inspections showed that the high requirements set for the inner quality of ZERODUR are completely fulfilled.
