- •
The effects of sintering parameters on the microstructure of magnesium aluminate spinel are investigated.
- •
By using single-step sintering method, the densification kinetics of MAS is different from grain growth kinetics.
- •
A MAS material with a high relative density and a homogeneous microstructure consisting of small grains is achieved under optimum two-step sintering.
- •
The flexure strength and Vickers hardness of the MAS sintered at optimum two-step sintering are improved.
