BaCO3
ceramic· BaCO3
Barium carbonate (BaCO₃) is an inorganic ceramic compound widely used as a raw material and functional additive in ceramics, glass, and chemical manufacturing. It serves as a source of barium oxide in glazes, enamels, and glass formulations, where it improves melt fluidity and thermal stability, and is also employed in electronics, pigment production, and as a precursor for other barium compounds. Engineers select BaCO₃ for applications requiring high-temperature stability, optical transparency enhancement, or controlled barium source delivery, though its use requires careful handling in applications where solubility or toxicity considerations apply.

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.
