Ceramics are hard, heat-resistant, and corrosion-resistant materials widely used in daily life and industry. Ten common uses of ceramics are pottery and tableware, bricks and tiles, sanitary ware, electrical insulators, cutting tools, heat-resistant linings, glass products, medical implants, abrasives, and aerospace components.
Ceramics are non-metallic, inorganic materials known for high temperature resistance, hardness, chemical stability, and electrical insulation. Because of these properties, ceramics are used across engineering, medical, electrical, construction, and daily-life applications.
