Ceramics

Why in News?

As of early April 2026, many ceramic factories in Morbi, India’s ceramic hub, have suspended operations for over 3 weeks due to severe gas supply shortages caused by the ongoing West Asia conflict.

• Ceramic – They are inorganic, non-metallic, solid materials.
• Raw materials – Clay, silica, feldspar, kaolin, alumina.
• Process – Shaping to drying to firing at high temperatures.
• Structure – Primarily crystalline, glassy, or a mixture of both.
• Properties – Extremely hard and strong in compression, but brittle (prone to fracturing).
• Durability – Chemically non‑reactive and heat‑resistant.
• Electrical – Generally good insulators, although some can be conductive or superconducting.
• Historical Significance – Ceramics date back to Neolithic Age, earliest pottery for storage and cooking.
• Used in Indus Valley Civilization for art, utility, and trade.
• Ancient civilizations (China, Mesopotamia, Egypt) perfected ceramic techniques for tiles, pottery, and ornaments.
• Symbol of cultural heritage and technological advancement.
• Critical Minerals and Ceramics - Ceramics rely on critical minerals like alumina, silica, zirconium, rare earths.
• Critical minerals policy directly impacts ceramic industry supply chains.
• Advanced ceramics essential for semiconductors, renewable energy, defense applications.
• India’s push for critical mineral exploration aligns with strengthening ceramic technology for strategic sectors.
• Morbi, The Ceramic Hub of India
  • Located in – Saurashtra region of Gujarat
  • Accounts for - 90% of India’s ceramic tile production.
  • Crisis – Dependent on propane‑LPG imports from Persian Gulf; disrupted by Strait of Hormuz blockade.
  • Exports to USA, Europe, Middle East.

India is world’s 2nd largest ceramic tile producer.

• Modern Applications of Ceramic
  • Construction – Tiles, sanitaryware, flooring.
  • Electronics – Capacitors, insulators, superconductors.
  • Medicine – Bio‑ceramics for dental implants, bone grafts.
  • Defence – Ceramic armour, heat‑resistant coatings.
  • Energy – Ceramic membranes, fuel cells.
  • Space – Thermal protection systems in spacecraft.
