DRY PROCESS FOR MAKING A LARGE XENOTIME CERAMIC BLOCK
A ceramic block consisting essentially of substantially homogeneous (Y2O3)x.P2O5, where 0.95≰x≰1.05, having length LL, a width WW and a height HH, and a volume VV of at least 8×10−3 m3 essentially free of cracks throughout the volume, a density of at least 85% of the theoretical maximal density of Y2O3.P2O5 under standard conditions, and a creep rate at 1250° C. and 6.89 MPa of CR, where CR≰8.0×10−6 hour−1, and method for making the same. The method utilizes a dry process where the starting YPO4-based ceramic material is synthesized by reacting anhydrous P2O5 with dry Y2O3 powder.
