Ceramics: Properties, Application and Classification of Ceramics
What is Ceramic? A ceramic is an inorganic, non-metallic solid mainly based on oxide, nitride, boride, or carbide that are shaped and then fixed at high temperatures. Ceramic is hard, brittle, heat-resistant, and corrosion-resistant. Ceramic is used almost everywhere like in kitchens, cookware, pottery, bricks, pipes, etc. Many ceramics contain a mixture of ionic and covalent bonds between them. That's why they exist in crystalline, semi-crystalline, and vitreous form. Properties of Ceramics 1. Ceramics have high hardness. 2. They are brittle and have poor toughness. 3. They have a high melting point. 4. They have poor electrical and thermal conductivity. 5. They have low ductility. 6. They have a high modulus of elasticity. 7. They have high compression strength. 8. They show optical transparency to a variety of wavelengths. Application of Ceramics 1. Silicon carbide and tungsten carbide are technical ceramics that are used in body armor, wear plates for mining, and machine ...
