摘　　要：透明陶瓷兼具高强度、高硬度和优异的光学性能,在轻量化透明装甲领域具有重要的应用前景。制备大尺寸和高光学质量透明陶瓷部件是实现其应用的主要挑战。本工作采用国产商业Al_(2)O_(3)和Y_(2)O_(3)为起始原料,通过真空反应烧结工艺制备钇铝石榴石(Y_(3)Al_(5)O_(12),简称YAG)透明陶瓷,突破了大尺寸素坯干压成型与脱黏、真空烧结及光学性能提升等关键技术,成功研制了低变形量、高光学质量的YAG透明陶瓷,并通过成型和烧结设备的升级改造,YAG透明陶瓷的最大可制备尺寸达到1040 mm×810 mm×15 mm,为后期应用奠定了坚实基础。Transparent ceramic materials have excellent strength,hardness and optical properties,which have important application prospect in light-weight transparent protective armor.However,the preparation of transparent ceramic components with large protection area and high transmittance properties is the main challenge to achieve application.In this work,large-size yttrium aluminum garnet(Y_(3)Al_(5)O_(12),abbreviated as YAG)transparent ceramics with low deformation and excellent optical quality were fabricated by reactive sintering in vacuum using domestic high-purity Al_(2)O_(3) and Y_(2)O_(3) powders as starting materials,and the key technologies including dry pressing,calcining,high-temperature vacuum sintering and optical performance were broken through.In addition,as the upgrading of molding and sintering equipment,the dimension of YAG transparent ceramic was enlarged to 1040 mm×810 mm×15 mm,laying a substantial foundation for future applications.
