Silicon Nitride Protection Tube

Silicon Nitride Thermocouple Protection Tube are extensively for continuous temperature measurement in non- ferrous metals. Silicon nitride is an important structural ceramic. It is super hard, resistant to wear and oxidation at high temperatures. Moreover, it has exceptional thermal shock resistance, when it is heated to above 1000 ° C in the air, and rapidly cooled and then heated rapidly without breaking.

Features:

• Superior thermal shock resistance
• High mechanical fatigue & creep resistance
• High tensile strength at high temperature
• Good chemical corrosion resistance
• Good electrical insulation
• High fracture toughness

Specifications:

• Volume density (g/cm³) : 77
• Flexural strength (MPa): 186.4
• Porosity (%): 12  %
• Thermal expansion coefficient (1×10^-6/K): 51 
• Fracture toughness (Mpa x m^-1) : 2.8
• Thermal Conductivity (W/mk): 15
