· CaCO3

Calcium carbonate (CaCO₃) is an abundant, inorganic ceramic compound commonly found in nature as limestone, chalk, and marble. It is widely used in construction materials, fillers, and chemical applications due to its low cost, availability, and adequate stiffness for non-structural roles. Engineers select CaCO₃ for applications where cost-effectiveness and chemical inertness are priorities, though its brittleness and moderate strength limit it to non-load-bearing or secondary structural roles compared to advanced ceramics.

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.
