Abstract

Optical and mechanical properties of transparent ceramic MgAl2O4 spinel versus SPS conditions have been investigated. Syntheses kinetics of MgAl2O4 has been studied at different heating duration, pressure force. Behaviour of spinel transparency, density, elasto-plastic properties in depend on the mentioned terms has been studied. High transparency (72.6% at wavelength of 555 nm) and high mechanical properties (fracture toughness of 2.4 MPa × m1/2, microhardness of 18.52 GPa, Young's modulus of 212 GPa) have been achieved by decreasing the sintering duration and optimization of the pressing force.
