发明名称 Surface-tensioned sapphire plate
摘要 A surface-tensioned sapphire plate and a corresponding manufacturing process. The plate may include a planar sapphire substrate and at least one layer disposed on the surface of the substrate for tensing the substrate. The layer may include at least 50 wt.-% of aluminum oxide (Al2O3). The manufacturing process for producing of a sapphire plate may include providing a planar sapphire substrate, and coating at least one surface of the substrate with a layer tensing the substrate. The layer may include at least 50 wt.-% of aluminum oxide (Al2O3).
