Ceramics are characterized by their unique chemical, physical, and mechanical properties that distinguish them from other materials. Understanding the science behind ceramics helps in appreciating their applications, durability, and versatility across various industries. This article explores the scientific principles, properties, and structural components that define ceramics.
1. Chemical Composition and Structure
Ceramics are primarily composed of inorganic materials, typically oxides, nitrides, carbides, or silicates, bonded through ionic or covalent bonds:
Silicates: Predominantly found in clay minerals like kaolinite, silica (SiO₂), and alumina (Al₂O₃), forming the basis of traditional ceramics.
Oxides: Common ceramic oxides include alumina (Al₂O₃), zirconia (ZrO₂), and magnesia (MgO), offering high-temperature stability and corrosion resistance.
Non-oxides: Silicon carbide (SiC) and boron nitride (BN) exhibit exceptional hardness, thermal conductivity, and resistance to wear and corrosion.
