Tellurite glass tubes, capillaries and rods manufacture comprises controlled heating of a tellurium, tungsten, sodium and niobium oxides composition, for solidification in a silica tube
NOVELTY – The tellurite glass tubes, capillaries and rods manufacture has radio-frequency induction heating of a 70:19:7:4 stoichiometric ratio TeO2-WO3-Na2O-Nb2O5 composition at approximately 900 degrees C for e.g. 30 minutes. The liquid glass is homogenized, for drawing through a silica tube from a platinum crucible, the resulting solidified glass rod then being processed by centrifugation to form the tubes. USE – In materials science.
Main Application Field
