Ceramics are materials that are inorganic and typically have a crystalline structure, processed at high temperatures, and are hard, brittle, and heat-resistant. They are generally electrically insulating. They are one of the four main material groups in materials science. Ceramics stand out due to their structural strength, thermal and wear resistance, and chemical stability. They are used in both high-temperature applications and traditional applications. In materials engineering, the mechanica
