Chapter XI ceramic insulation

During 1958 the trend to more rigorous operating environments was reflected in continued attention to the high-temperature properties of ceramics in general and to the effects of radiation on glass in particular. There was further interest in non-silicate glasses, and the understanding of the sintering process in the absence of a glassy phase was enlarged. The usual incremental improvements in compositions and processing continued to be made, and the general study of the properties of materials continued to attract interest.
