Abstract:
A mold for shaping glass-based material can include a mold body having a surface, wherein at least a portion of the mold body near the surface comprises at least about 90% by weight nickel and from about 0.2% to about 0.35% by weight manganese; and a nickel oxide layer on the surface of the mold body. The nickel oxide layer has first and second opposing surfaces wherein the first surface of the nickel oxide layer contacts and faces the surface of the mold body and the second surface of the nickel oxide layer includes a plurality of grains. The plurality of grains has an average grain size of about 150 μm or less.
Abstract:
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 mold compositions minimize imperfections in the formed glass substrates providing optical quality shaped glass articles for use in electronics applications.
