FAQ About Silicon Nitride Balls

Silicon nitride (Si₃N₄) balls are distinguished by their high hardness (>2000 Knoop), low density (3.2 g/cm³), and superior fracture toughness, which remain stable even at elevated temperatures. These properties, combined with their low thermal expansion coefficient and excellent wear resistance, make them ideal for high-stress applications. Additionally, their high electrical resistivity and outstanding chemical stability enhance their performance in precision engineering and extreme environments.
