| Summary: | A bushing for drawing glass fibers and its use. The bushing is made of at least two different metallic materials from the group comprising platinum, platinum-iridium alloy, platinum-ruthenium alloy, and platinum-rhodium alloy, such that
′;(a) the sidewalls are made of platinum or platinum-iridium alloy or platinum-ruthenium alloy or platinum-rhodium alloy,
(b) the tip(s) are made of platinum or platinum-rhodium alloy,
(c) the power supply terminals are made of platinum or platinum-rhodium alloy, and
(d) the tip plate is made of platinum-iridium alloy or platinum-ruthenium alloy or platinum-rhodium alloy. If the sidewalls and the tip plate are made of platinum-iridium or platinum-ruthenium alloy, they have a coating of platinum or platinum-rhodium alloy at least on their exterior surface. |
