· JVASP-15590· USi2Au2

USi₂Au₂ is an intermetallic compound combining uranium, silicon, and gold—a specialized material from the uranium-based intermetallics family typically explored in research rather than widespread industrial production. This compound represents a study in high-density metallic systems with potential applications in nuclear materials science, radiation shielding, or advanced electronic/thermal management where uranium's unique nuclear and thermal properties can be leveraged. Engineers would consider this material primarily in specialized defense, nuclear, or experimental contexts where the combination of uranium's density and intermetallic hardening provides advantages over conventional alternatives, though regulatory and handling requirements are significant factors in material selection.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
