HIGH PURITY NICKEL MOLDS FOR OPTICAL QUALITY GLASS FORMING AND METHOD OF SHAPING A GLASS SHEET USING SAID MOLDS

摘要

The present disclosure relates to high purity nickel molds for use in forming three dimensional glass substrates, along with methods of making three dimensional glass substrates. The high purity mold compries a nickel oxide layer on the shaping surface, the nickel oxide layer having a thickness from about 200 nm to about 20 micrometers. The mold compositions minimize imperfections in the formed glass substrates providing optical quality shaped glass articles for use in electronics applications.
