Ceramics are a diverse category of engineering materials with a wide range of technical applications. Derived from the Greek word “keramos,” meaning pottery or clay, ceramics encompass a wide range of inorganic, non-metallic materials characterized by their exceptional hardness, high melting points, and often remarkable resistance to heat, corrosion, and wear. These unique properties make ceramics indispensable in various industrial applications, from electronics and aerospace to automotive and biomedical fields.
Polycrystalline Diamond
Formation and Structure Polycrystalline diamond is synthesized through a high-pressure, high-temperature (HPHT) process, which results in the growth of numerous diamond crystals that interlock to form a dense and robust structure. This distinctive polycrystalline arrangement grants PCD its superior hardness, making it a compelling choice for applications requiring resistance to wear and abrasion. Hardness and...
Aluminum Oxide
Introduction Aluminum oxide (Al₂O₃) is one of the most widely used industrial materials due to its exceptional hardness, chemical stability, and thermal resistance. Found naturally as the mineral corundum, aluminum oxide is produced synthetically in various grades for applications ranging from abrasives and cutting tools to ceramics, electronics, and refractory materials. Its high melting point...

Tungsten Carbide

Introduction Tungsten carbide (WC) is a hard, dense, and wear-resistant material composed of tungsten (W) and carbon (C) in equal parts. It is known for its exceptional hardness, high melting point (≈ 2870°C or 5198°F), and outstanding resistance to wear and deformation. These properties make tungsten carbide an essential material in metalworking, mining, aerospace, defense,...
Silicon Carbide
Introduction Silicon carbide (SiC) is a hard, chemically resistant, and thermally stable material with a broad range of industrial applications. As a compound of silicon (Si) and carbon (C), SiC exists naturally as the rare mineral moissanite but is primarily produced synthetically for industrial use. Its extreme hardness (Mohs scale 9.2), high thermal conductivity, electrical...
