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Al2O3和Y2O3为起始原料, 通过真空反应烧结工艺制备钇铝石榴石(Y3Al5O12, 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。

Abstract:

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 (Y3Al5O12, abbreviated as YAG) transparent ceramics with low deformation and excellent optical quality were fabricated by reactive sintering in vacuum using domestic high-purity Al2O3 and Y2O3 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.

Key words: YAG, large size, reaction sintering, transparent ceramic
