· JVASP-93461· HoIO

HoIO is a rare-earth ceramic compound composed of holmium and iodine oxide, belonging to the class of ionic ceramics with potential applications in advanced functional materials research. This material is primarily of interest in academic and developmental contexts as a layered or semi-layered ceramic, where its moderate stiffness and relatively low density make it a candidate for studying structure-property relationships in rare-earth halide systems. Unlike conventional structural ceramics, HoIO's exfoliation characteristics suggest potential utility in layered-material research and as a precursor platform for exploring rare-earth ceramics in emerging technologies such as optical, thermal, or electronic applications.

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.
