· JVASP-63193· Dy2B4C

Dy2B4C is a rare-earth boron carbide ceramic compound combining dysprosium with boron and carbon phases. This material belongs to the family of advanced refractory ceramics and is primarily explored in research contexts for high-temperature applications where thermal stability, hardness, and neutron absorption properties are valued. Industrial adoption remains limited; the material is of particular interest in nuclear engineering, aerospace thermal barriers, and specialized wear-resistant applications where rare-earth additions provide enhanced oxidation resistance or radiation shielding compared to conventional boron carbide formulations.

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.
