窒化珪素セラミック製プランジャー

設計上の特徴

Silicon nitride ceramic plunger, also known as an insulating ceramic piston, demonstrates the outstanding performance of silicon nitride ceramics as industrial-grade fasteners:

Excellent Mechanical Strength and Wear Resistance

With a high elastic modulus of 290 GPa and Vickers hardness reaching 1500 HV, these properties provide exceptional wear resistance and compressive strength, ensuring stability and long-term durability under high-load conditions.

High Heat Resistance and Thermal Shock Resistance

Capable of operating at temperatures up to 1200°C with a high coefficient of thermal shock stability up to 500°C, the plunger maintains dimensional stability and performance in environments with significant temperature fluctuations.

Superior Chemical Stability

The chemical inertness of silicon nitride allows it to perform well in various corrosive environments, making it particularly suitable for applications in chemical processing and medical equipment.

Excellent Sealing Performance and Low Friction

The smooth outer surface and precise machining dimensions of the plunger contribute to excellent sealing performance, reducing friction and wear during operation, thereby enhancing overall system efficiency.
