Ceramics are inorganic, non-metallic materials formed by the action of heat. They are typically hard, brittle, and resistant to high temperatures and chemical attack.
Key Characteristics / Core Concepts
- Inorganic: Made from non-living materials.
- Non-metallic: Do not conduct electricity well.
- High-temperature processing: Formed through firing (heating to high temperatures).
- Crystalline or glassy structure: Their atomic structure determines their properties.
- Variety of applications: Used in countless everyday and specialized applications.
How It Works / Its Function
Ceramics are created by shaping a mixture of raw materials (clays, minerals, etc.) into the desired form, then firing it in a kiln at high temperatures. This process causes a chemical change, resulting in a hardened, durable product.
Examples
- Clay pottery: Dishes, vases, and other decorative or functional items.
- Bricks and tiles: Construction materials for buildings and flooring.
- Ceramic insulators: Components used in electrical systems to prevent short circuits.
Why is it Important? / Significance
Ceramics are vital across numerous industries because of their unique combination of strength, durability, and heat resistance. They contribute to construction, electronics, and much more.
Their versatility and ability to withstand extreme conditions makes them indispensable for many modern technologies.
