· O8 Ho2 Ta2

O8Ho2Ta2 is a rare-earth ceramic compound combining holmium and tantalum oxides, representing an experimental material in the high-performance oxide ceramic family. While not widely commercialized, this composition is of research interest for applications requiring thermal stability, chemical inertness, and high-temperature mechanical integrity—characteristics typical of tantalum-based oxides used in extreme environments. Engineers investigating advanced ceramics for aerospace, refractory, or specialized electronic applications may encounter this material in literature or emerging material platforms, though conventional tantalum oxide or holmium-doped ceramics often serve as more established alternatives.

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.
