Abstract

AbstractThis article discusses the successful preparation of high‐strength solid solution spinel ceramics via a solid‐state reaction sintering process employing MgAl2O4. The effects of ZnO content on the sintering behavior, bulk density, apparent porosity, phase composition, microstructure, cold modulus of rupture, and modulus of elasticity of the MgAl2O4‐based ceramics are investigated. The results show that the formed MgAl2O4‐based ceramics represent an MgAl2O4–ZnO solid solution, which markedly improves the sinterability, densification, and mechanical properties of the pure MgAl2O4 ceramic and decreases the sintering activation energy.
