摘要：
Results are provided for study of a series of high refractoriness objects for thermal shock resistance and determination of their actual heat capacity. It is shown that under high temperature conditions and sharply varying thermal loads good resistance develops for objects with the highest ratio of heated surface area to volume. Two-phase materials demonstrate the best thermal shock resistance. Periclase objects with a protective coating based on ZrO2 have thermal shock resistance comparable with that of zirconia objects.
