    摘要: The coated noble metal element used in glass manufacture, such as a noble metal pipe, has an uncoated side that contacts a glass melt and an H2-impervious layer or an H2-impervious and O2-impervious layer, which is provided on a side opposite from the uncoated side. The H2-impervious layer or H2-impervious and O2-impervious layer is heat-resistant and is liquid or solid. In one process for providing the layer on the noble metal element an empty space between the noble metal element and a ceramic insulating jacket is filled with a coating material, and then the coating material is melted so that it wets a surface of the noble metal element. The coating material can include glass cullet, crushed glass or glass powder or is a mixture of crushed glass and ground ceramic material.

    摘要: The regionally coated noble metal element for use in glass production has an uncoated region for contacting a glass melt and a side opposite from the uncoated region is provided with an H2-impervious layer or an H2-impervious and O2-impervious layer. The H2-impervious layer or H2-impervious and O2-impervious layer has a thickness greater than or equal to 1 mm, is heat-resistant, liquid, or solid. This layer is made from at least one partly or completely crystallized glass or a glass mixture or a ceramic material. Processes for coating the noble metal element are also described. The coated metal elements can be an electrode in a distributor, a channel or melting tank, a pipe for conducting and conditioning glass melts, a shaping tool for producing pipes and rods or a jacketed platinum tube for direct heating of bottom outlets, transport equipment or charging organs, an agitator, a pipe-drawing head, a feeder head, a plunger in gob feeders, drawing tanks and drawing lips for flat glass production and fining chambers.

    摘要: The apparatus for reduced-pressure refining of a glass melt includes a refining bank formed so that a reduced pressure is generated by a glass flow in it. The refining bank has a component, which is made from a refractory metal or refractory alloy acting as glass-contact material. The refractory metal or alloy contains molybdenum, tungsten, tantalum, and/or hafnium. The device of the present invention includes a protective gas reservoir for a protective gas and an automatically operating valve connecting the reservoir with the refining bank so that an inner side of the component that would otherwise be exposed when a pressure rise or a falling glass melt column occurs is protected from oxidation by the protective gas. A process for using the device during refining of the glass melt is also part of the invention.
