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.
