Influences of Process Parameters on the Forming of YAG Phase

Abstract:

Submicron single-phase yttrium aluminum garnet (Y3Al5O12, YAG) powders were fabricated by solid-state reactive heat-treating a mixture of pyrolysis product, heat-treating isopropyl aluminum at 500°C, and yttria (Y2O3) powders. The powders were mixed by ball milling for 2~3 h doped with 5wt% aluminium fluoride (AlF3), and then heat-treated at 1200°C for 2~5 h. Characterized by XRD, mixing the powders by ball milling and doped with AlF3 lowered the heat-treating temperature and made the forming of YAG phase be single.
