Claims22
Fused, crystalline eutectic material comprising eutectic of at least (i) crystalline, complex Al2O3.rare earth oxide, and (ii) at least one of aluminoxy-D or M-aluminoxy-D, wherein D is at least one of carbide or nitride, and M is at least one metal cation other than Al.
A method for making fused, crystalline eutectic material comprising eutectic of at least (i) crystalline, complex Al2O3.rare earth oxide, and (ii) at least one of aluminoxy-D or M-aluminoxy-D, wherein D is at least one of carbide, or nitride, and M is at least one metal cation other than Al, said method comprising:
- melting at least one Al2O3 source and at least one rare earth oxide source to provide a melt, wherein at least one source of nitrogen or carbon is provided in said melt;
- and
- converting the melt to said fused, crystalline material.
