Aspects of the corrosion of refractories in structured aggressive media

This article examines aspects of the testing of refractories for corrosion resistance by different methods. Studies were made of the corrosion resistance of refractories under dynamic conditions by using a special unit based on rotation of the test specimen in a melt of the corrodent (boron-bearing ultrahard flint, 65% PbO, 35% B2O3). It was determined that corrosion rate increases in proportion to the depth of immersion of the specimen in the melt. Anew method is proposed for determining corrosion rate, the method making it possible to significantly shorten corrosion tests and improve the accuracy of the results.
