In this study. Spark Plasma Sintering (SPS)  of both slip casted and powder specimens of alumina/ yttria core-shell nanocomposite were utilized for fabricating transparent Yttrium Aluminum Garnet (YAG) ceramics. Phase evolution. optical transmittance and the microstructure of sintered samples were compared. https://www.relicsbook.com/product-category/autographed-framed-football-photos/
