Silicon nitride ceramics possess extreme hardness, ranking just after diamond and silicon carbide, which makes them exceptionally durable and ideal for high-wear applications like bearings and cutting tools.
Due to its extremely low thermal expansion coefficient and high thermal conductivity, silicon nitride exhibits outstanding thermal shock resistance, allowing it to undergo rapid temperature changes without cracking.
Silicon nitride maintains excellent mechanical strength, structural integrity, and shape stability at elevated temperatures even exceeding 1200°C.
Yes, it demonstrates outstanding corrosion resistance against most acidic and alkaline environments, as well as molten metals.
Yes. Because of its bioinertness and high biocompatibility, silicon nitride is highly suitable for medical implants and other bio-related applications.
In high-temperature oxidizing environments, silicon nitride forms a dense oxide layer on its surface, which acts as a protective barrier to prevent further oxidation.
