ceramic· JVASP-134325· CaCO
Calcium carbonate (CaCO₃) is an inorganic ceramic compound and one of the most abundant minerals in nature, commonly occurring as limestone, chalk, and marble. It is widely used as a filler, reinforcing agent, and functional additive in polymers, coatings, adhesives, and construction materials, valued for its cost-effectiveness, availability, and ability to improve stiffness and processing characteristics. Engineers select CaCO₃ over alternatives when seeking an economical way to increase material volume, improve dimensional stability, or reduce resin content in composites, though its use is generally limited to non-critical, non-load-bearing applications where its moderate strength is acceptable.

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.
