研究了粉末预热对火花等离子烧结制备的MgAl2O4尖晶石陶瓷显微结构和光透射率的影响。粉末在空气中的预热增强了透光性，但对微观结构没有显著影响。预热后烧结尖晶石的光吸收下降，烧结过程中未见碳污染。
The effects of preheating of powder on microstructure and optical transmission for MgAl2O4 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.
