· JVASP-55704· HIO3

Iodic acid (HIO₃) is an inorganic ceramic compound belonging to the oxyacid family, characterized by its crystalline ionic structure. While primarily known as a chemical reagent rather than a structural ceramic, HIO₃ finds niche use in specialized applications requiring iodine-based compounds, including analytical chemistry, oxidizing agent formulations, and experimental studies into halogen ceramics. Its selection is driven by specific chemical requirements rather than mechanical performance, making it relevant for applications where iodine chemistry, rather than structural load-bearing, is the engineering need.

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.
