Abstract

Rutile was selected for some practical studies of processing and properties of ceramic containers. Hot isostatic pressing at 1280°C has resulted in reaction zones between the TiO2 powder and the steel canning. The phases ilmenite, pseudobrookite, rutile, and iron have been identified by X-ray diffraction and by microprobe analysis.

The microstructures have been interpreted by classical metallographic methods, and some microstructures obtained by hot pressing and rapid cooling have also been examined for purposes of comparison.

Some implications of the microstructures have been discussed in terms of microcracking and slow crack growth.
