COATINGS FOR GLASS SHAPING MOLDS AND MOLDS COMPRISING THE SAME
Precision glass molds are described, which are formed by coating a mold made from high purity, fme grain sized graphite, with a coating including titanium. In various implementations, the titanium coating is overcoated with yttria (Y2O3) to provide a high precision glass mold of superior performance character. The resultant glass molds can be used to form glass articles having a highly smooth finish, for high precision applications such as consumer electronic device applications, medical instruments, and optical devices. The use of high purity, fme grain size graphite allows molds to be machined at low cost, thereby eliminating the need to fabricate a metal mold that must be coated with multiple layers including metal diffusion barrier layers to meet operational requirements for such precision applications.
