Reactive processing of ceramic binding systems for
The general applied objective of this project is to develop hydratable alumina-bonded castables of properties comparable to the high-temperature fired basic bricks. This work is focused on improving the sintering of the ceramic binding systems at relatively low temperatures ( 1300°C) through incorporation of ultrafine powders. Ultrafine magnesium aluminate spinel powders were synthesized
