ceramic· JVASP-20798· DyB4
DyB4 is a rare-earth boride ceramic compound combining dysprosium with boron in a 1:4 stoichiometric ratio. This material belongs to the family of refractory borides, which are investigated for extreme-temperature and high-hardness applications where conventional ceramics reach their limits. DyB4 is primarily of research and development interest rather than established in high-volume production, with potential applications in specialized aerospace, nuclear, and wear-resistant coating systems where thermal stability and hardness are critical.

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.
