Abstract
  • The behaviour of several types of silicon nitride-based materials in contact with molten copper has been evaluated. Tests were performed at a temperature of 1400 K for a holding time of 260 h in fluido-dynamic conditions. The extent of corrosion has been evaluated in terms of linear loss, weight loss, morphology and chemical composition of the surfaces remaining in contact with the molten phase, by means of SEM, EPMA and X-ray diffraction. Corrosion resistance has been found to be a function of the chemical composition, type and amount of the secondary phases. Materials produced with MgO as a sintering aid showed poor resistance whereas those with Al2O3 exhibited the best performance. In any case the extent of corrosion was very slight and the results revealed that all the tested ceramics may be considered suitable for use in contact with molten copper. (literal)
