Carbonated apatite and brushite are the different atomic phases of calcium phosphate and they are:
Carbonated apatite and brushite are the different atomic phases of calcium phosphate and they are:
Show Hint
Calcium phosphates are basically mineral crystals. Just like household porcelain or pottery, mineral crystals are inorganic and non-metallic, which means they are classified as ceramics!

The Correct Option is C
Solution and Explanation
Concept:
Biomaterials are broadly categorized based on their atomic bonding and structural composition into polymers, metals, ceramics, or composites. Calcium phosphates are inorganic, non-metallic compounds made from calcium ions linked to phosphate groups.
Step 1: Characterizing the material phases.
• Carbonated Apatite: An inorganic mineral phase closely resembling the natural mineral crystalline component of human bone and teeth enamel.
• Brushite: A dicalcium phosphate dihydrate (\( \text{CaHPO}_4 \cdot 2\text{H}_2\text{O} \)) crystalline phase often utilized as a bioresorbable bone cement component.
Step 2: Categorizing via Material Science definitions.
By fundamental definition, inorganic, non-metallic crystalline solids prepared through high-temperature treatment or ionic precipitation processes are classified strictly as ceramics (or bioceramics when optimized for medical implantation). They are brittle, show excellent biocompatibility, and link naturally with native bone tissue through osteoconduction. This clearly places them under Option (C).
