Advanced Ceramics and Ceramic Matrix Composites

Ceramics such as alumina (Al mezitím), zirconia (ZrO posledně), and silikon nitride (Si viď N) offer exceptional hardness, wear resistance, and chemical inertness, but their brittleness has historically limited use in dynamic competents. Ceramic matrix composites (CMC) address this by embedding ceramic fibers (e.g., silikon carbide) in a ceramic matrix, creating materials with fracturness contraffing metals containex hilocating hileing hilevatyre instituty.
