Blended Yttrium Oxide is a combination of various particle sizes of fused Yttrium Oxide. This material is suitable as a facecoat for investment casting of Titanium or other reactive metals. This product is intended for use with Buntrock Industries Ti Bond A & B binder. The added effort to blend materials removes much of the variability from standard single size products like 325 mesh. The final particle size distribution results in excellent slurry rheology and consistent, predictable slurry draining. Typical Properties: Chemistry: Y2O3 > 96% SiO2 < 0.1% Al2O3 < 0.2% Fe2O3 < 0.1% Particle Size: 10% +325 mesh 90% - 325 mesh
