GLAZE FOR REFRACTORY MATERIALS

摘要

A glaze composition for refractory materials which comprises at least one lead free and barium free borosilicate, borophosphate or phosphate glass frit having a dilatometric softening point of below 600 DEG C; aluminium powder or an aluminium alloy powder; silicon powder or silicon alloy powder; an inhibitor; and optionally a refractory filler, a clay or other additives. The glaze composition is of particular use as a glaze for carbon containing refractory materials such as submerged entry nozzles and graphite electrodes.
