Historically, ceramics encompass clay-centered items like pottery, bricks, and tiles. Having said that, the modern definition extends much outside of these conventional programs.
Ceramics are characterised by their atomic composition—typically crystalline or partially crystalline—with bonding that is definitely predominantly ionic or covalent. This bonding configuration imparts the distinct properties linked to ceramics: superior hardness, excellent chemical resistance, electrical insulation, and the chance to stand up to Excessive temperatures . The potent atomic bonds require substantial Strength to break, detailing why ceramics normally have substantial melting factors and continue being steady in corrosive environments the place metals would promptly degrade.
