· Ba

Barium is a soft, silvery-white alkaline earth metal with relatively low density and moderate stiffness. Industrial applications are limited for barium metal itself; instead, barium is primarily valued in compound forms (barium oxide, barium sulfate, barium carbonate) where it serves as a critical additive in ceramics, glass, pigments, and drilling fluids. Engineers select barium compounds for their ability to increase refractive index and opacity, provide X-ray shielding, or modify material properties in specialized coatings and composites.

Regulatory Screening

Environmental

Export Control

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.
