The effects of preheating of powder on microstructure and optical transmission for MgAl 2 O 4 spinel ceramics fabricated by spark plasma‐sintering processing are investigated. The preheating of powder in air enhances light transmission, whereas it has no remarkable effects on the microstructure. A decrease in light absorption was also observed for the spinel sintered after the preheating, and carbon contamination during sintering was not observed.
