Role of different rare earth oxides on the reaction sintering of magnesium aluminate spinel
Ceramics International, 2019Role of three rare earth oxides, viz., La2O3, CeO2 and Yb2O3 on reaction sintering of magnesium aluminate spinel having molar ratio of MgO:Al2O3 = 1:2 from its solid oxide precursors was investigated in static and dynamic heating conditions.

Preparation of lithium disilicate glass-ceramics was attempted via solid-state reaction between Li2SiO3 crystals and SiO2 glass. By addition of 0.5 mol Li2Si2O5 glass as binding, the mixtures were hot-pressing sintered at 840 °C for 1 h.

Reaction sintering: correlation between densification and reaction
Journal of Materials Science, 1979By studying simultaneous densification kinetics and reaction kinetics during the sintering and hot pressing of alumina-zircon mixtures, it has been possible to distinguish between the particle rearrangement and particle reshaping (diffusive) stages of the densification process. Particle rearrangement is found to be more significant during hot pressing (
