· JVASP-123904· MgB

MgB₂ is an intermetallic ceramic compound composed of magnesium and boron, belonging to the family of borocarbides and intermetallic ceramics. It is primarily investigated as a superconducting material for research and specialized applications, particularly valued for its relatively high critical temperature and potential use in high-field magnet systems. Unlike conventional superconductors, MgB₂ offers advantages in cost and ease of fabrication, making it attractive for applications where extreme cooling requirements or material brittleness of traditional superconductors are limiting factors.

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.
