Na4 U4 B4 O20
semiconductor· Na4 U4 B4 O20
Sodium uranyl borate (Na₄U₄B₄O₂₀) is a mixed-metal oxide compound containing uranium and boron—a relatively uncommon material that bridges nuclear chemistry and ceramic science. This compound is primarily investigated in nuclear fuel chemistry and materials research contexts rather than established commercial applications; its semiconductor classification suggests potential interest in radiation detection or specialized electronic applications under research conditions. Engineers would consider this material only in specialized nuclear, radiochemistry, or experimental condensed-matter applications where uranium-bearing ceramics offer unique nuclear or structural properties unavailable in conventional alternatives.

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.
