ErTa3
ceramic· JVASP-37898· ErTa3
ErTa3 is an intermetallic ceramic compound combining erbium and tantalum, belonging to the rare-earth transition-metal ceramic family. This material is primarily investigated in advanced high-temperature and neutron-absorbing applications, where its combination of refractory properties and nuclear cross-section make it relevant to nuclear engineering, aerospace thermal protection, and control rod systems. ErTa3 represents a specialized research compound rather than a widely commercialized grade, offering potential advantages in extreme environments where conventional ceramics or metallic alloys reach thermal or neutronic limits.

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.
