Some Distinctive Contours Worn on Alumina-Silica Refractory Faces by Different Molten Glasses: Surface Tension and the Mechanism of Refractory Attack

JSGT 1954 V38 T089-T100

 Characteristic types of attack produced isothermally by some mobile glasses on alumina-silica refractories are listed. Holes and scores worn beneath the glass are narrower than arches formed above. The different kinds of attack are explained by hypotheses involving surface forces. Some complications often found in manufacture (coarse refractories, large temperature differences, etc.) were excluded as far as possible, in order to obtain a clearer picture of the main types of refractory attack.
