· JVASP-66157· Ba4HfTa

Ba4HfTa is a complex oxide ceramic compound combining barium, hafnium, and tantalum—a rare quaternary ceramic system primarily explored in materials research rather than established industrial production. This material family is of interest for high-temperature applications and specialized ceramic architectures where the combination of refractory metals (hafnium and tantalum) with alkaline earth elements (barium) offers potential for thermal stability, chemical inertness, or electrical properties. As a research-phase compound, Ba4HfTa represents the broader class of advanced ceramics being investigated for next-generation applications where conventional oxides fall short.

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.
