The effect of the loading rate on the strength of an alumina ceramics of grade GB-7 in air is studied. It is established that the strength of the ceramics decreases substantially with increase in the loading rate due to the interaction between the calcium borosilicate vitreous phase and steam, which causes substantial growth of the microstructural defects existing in the ceramics.
