Abstract

Aluminum oxide was uniformly coated on the surface of the spinel particles by a precipitation method followed by a heat treatment at 1200°C for two hours. The powder was then spark plasma sintered at temperatures as low as 1250-1350°C. The characterization of the coated powder and sintered pellets was carried out by scanning electron microscopy, X-ray diffraction, micro indentation, and light transmittance techniques. The in-line transmittance of 65.5% at 550nm, and the HV1 value of 15.58 ± 0.14 GPa were achieved for spinel doped with 3wt% Al₂O₃ and SPSed at 1350°C. Higher hardness values, HV1 ≥ 16GPa, were obtained at lower SPS temperatures.
