USi2
ceramic· USi2
USi₂ (uranium disilicide) is an intermetallic ceramic compound combining uranium with silicon in a 1:2 stoichiometric ratio. It belongs to the family of transition metal silicides and represents a material of primarily research and nuclear engineering interest rather than widespread commercial use. This compound is explored for specialized high-temperature applications and nuclear fuel contexts where its unique combination of metallic and ceramic characteristics—including high density and stiffness—may offer advantages in extreme environments.

Regulatory Screening
Environmental
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.
