WebDec 4, 2012 · In the following, we analyze the composition of the laser welded region, using Raman microscopy . We examined the welding of ULE to Zerodur as both glasses can be easily distinguished in the Raman spectra due to their different characteristic features. The Raman spectra of ULE and Zerodur can be seen in Fig. 6. We also … WebSchott mainly concentrated its research on glass ceramics in the Li 2 O-Al 2 O 3-SiO 2-composition field and contributed to a broadened understanding of the nucleation and crystallization phenomena; ... “Glass ceramic Zerodur M®”, Product Information No. 10008 (1989), available on request from Schott Glaswerke, Mainz.
