Morphology Evolution of the Hydration Products of Hydratable Aluminas at 40 °C

Hydratable Alumina (HA) is an important CaO-free hydration binder for no-cement castables. Different sources of hydratable alumina have varied phase compositions and physical properties (such as specific surface area and particle size), which could generate hydration products with different phases and structures during hydration.

Comparison of Cement- and Hydratable Alumina-Bonded Alumina-Spinel Materials for Steel Ladle Purging Plugs

This paper provides a summary of extended investigations performed on cement- and hydratable alumina bonded refractory materials for steel ladle purging plugs.
