Silicon Nitride and Sialon Ceramics Expand into Automotive and Rail Markets

Automotive and rail industries are turning to advanced ceramics for components that require high strength, low friction, and resistance to thermal shock. Silicon nitride balls are now used in hybrid ceramic bearings for electric vehicle motors, while sialon inserts improve the durability of diesel engine valves. Manufacturers are investing in near-net-shape forming techniques to reduce machining costs and broaden adoption.
