Abstract
Synthetic sintered YPO4 composite materials comprising excess amount of Y2O3 in the composition and process for making such materials. The Y2O3-modified sintered YPO4 composite material exhibits improved mechanical properties compared to stoichiometric YPO4 materials. The modified YPO4 materials can be used to produce different components used in the glass-making process such as, for example, an isopipe.
Claims12
A sintered YPO4 composite material comprising a plurality of grains, having a composition comprising (Y2O3)m·(P2O5)n, where m and n are mole fractions of Y2O3 and P2O5 in the composite material, respectively, and 0<De(P)=((m−n)/n)×100%≦0.5%.
