  • Glass-melting component
    Patent number: 11072553
    Abstract: A process for producing a glass melting component composed of refractory metal. A surface zone of the glass melting component is densified at least in sections by application of local compressive stress. As a result the surface zone has its porosity reduced compared to a volume section which is located underneath the surface zone and which has residual porosity.
    Type: Grant
    Filed: March 23, 2017
    Date of Patent: July 27, 2021
    Assignee: Plansee SE
    Inventors: Hannes Traxler, Michael Mark, Robert Schiftner, Wolfram Knabl
  • Crucible
    Patent number: 10844518
    Abstract: A crucible includes a wall made of a base material of tungsten or molybdenum or of a material based on tungsten or molybdenum. A barrier layer is disposed at least in sections on an outer side of the wall and/or in the wall. The barrier layer is made of a metallic material having a greater affinity for carbon and/or oxygen than the base material. A method for using a crucible for producing single-crystal sapphire or fused quartz and a method for producing a crucible for high-temperature applications are also provided.
    Type: Grant
