Preparation and properties of low cement castable sintered at different temperatures [PDF]

Processing and Application of Ceramics, 2009
The low cement high alumina castable (LCC) studied in this paper was synthesised, cured and then treated at different sintering temperatures. Since any inhomogeneity introduced during the castable preparation can remain inside the material degrading its ...
