Silicon Nitride Bonded Silicon Carbide (NSiC) Nozzles
Silicon Nitride Bonded Silicon Carbide (NSiC) Nozzles
Product Overview
Our NSiC nozzles are high-performance ceramic components designed for abrasive, corrosive, and high-temperature flow applications. Bonded with a silicon nitride (Si₃N₄) matrix, they provide an optimal balance of erosion resistance, thermal stability, and chemical inertness, delivering extended service life in the most demanding industrial environments.
Key Properties
-
Max Service Temperature: Up to 1,450°C (1,500°C intermittent)
-
Excellent Erosion & Abrasion Resistance: Ideal for high-velocity particulate flow
-
Outstanding Thermal Shock Resistance: Withstands rapid temperature fluctuations without cracking
