Abstract
Abstract Glass fibre drawing process, involving passage of the melt through perforations in a plate, incorporates the use of a Rh, Ir, Au alloy, with additions of Cu and Pt as required. Typically, the alloy would consist of up to 25% Rh, up to 20% Ir, the sum of these not exceeding 25%, 2-10% Au, and if required, 5% Cu or Pt. The glass in the drawing tank is conditioned so that the temp. of the plate remains below 1060-1160 degrees C. The diameter of perforations in the plate is between 1.5 and 1.96 mm.
