Which term refers to a hard, brittle, heat- and corrosion-resistant material such as clay?

• A. Ceramic
• B. Gold
• C. Filler
• D. Esthetic

Answer: (A)

Ceramic is the term that fits this description. Ceramics are hard, brittle solids known for their ability to withstand high temperatures and resist corrosion. They are typically inorganic and non-metallic, and clay becomes ceramic when it is fired, forming materials like porcelain, bricks, or ceramic tiles. The brittleness comes from the strong bonds in the crystalline structure, which make them stiff and resistant to deformation but prone to fracture. Gold is a metal and is malleable and ductile rather than brittle, Filler describes a material used to fill gaps, and Esthetic refers to appearance rather than a material type.
