ceramic· JVASP-121639· Ba4SrHf5O15
Ba₄SrHf₅O₁₅ is a complex mixed oxide ceramic composed of barium, strontium, hafnium, and oxygen—part of the perovskite-family materials that combine rare earth or high-valence cations for specialized functional properties. This is primarily a research and development material rather than an established commercial ceramic, investigated for applications requiring high thermal stability, chemical inertness, and dielectric or structural performance at elevated temperatures. The hafnium-rich composition positions it for niche aerospace and extreme-environment applications where conventional oxides reach their 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.
