· Ba4 Ho2 B4 Cl2 O12

Ba₄Ho₂B₄Cl₂O₁₂ is a rare-earth borate chloride ceramic compound containing barium, holmium, boron, chlorine, and oxygen. This is an experimental research material rather than an established commercial ceramic; it belongs to the family of rare-earth borates, which are of interest for optical, luminescent, and solid-state applications. The inclusion of holmium (a lanthanide) suggests potential utility in photonic or thermal applications, though industrial adoption remains limited and primary interest is in fundamental materials science and specialized functional ceramic development.

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.
