Patent Number: 8,796,168

Title: Modified synthetic xenotime material, article comprising same and method for making the articles

Abstract: Synthetic sintered YPO.sub.4 composite materials comprising excess amount of Y.sub.2O.sub.3 in the composition and process for making such materials. The Y.sub.2O.sub.3-modified sintered YPO.sub.4 composite material exhibits improved mechanical properties compared to stoichiometric YPO.sub.4 materials. The modified YPO.sub.4 materials can be used to produce different components used in the glass-making process such as, for example, an isopipe.
