The Rosseland mean opacity of hohlraum gold wall can be increased by adding other materials such as gadolinium to gold. At 0.1g/cm3 density and various radiation temperatures, the AuGd mixtures with equal fractional number density yield highest opacities. Using onedimension radiation hydrodynamics code RT87 combined with the Rosseland mean opacity database and state equations at multipleionized area, the radiation temperature of pure Au and AuGd mixture wall hohlraum were investigated under the condition of Xray source produced at ShenguangII laser facility. The simulation results show radiation energy loss of the wall decrease and radiation temperature increase 0.1~0.2MK for AuGd mixture hohlraum.
