      High Thermal Conductivity Silicon Nitride

      Goodfellow can now offer high thermal conductivity Silicon Nitride. This material is ideal for specialist applications, and offers several benefits.

      • High thermal conductivity of 100W/mK. Which is 4X higher than standard Silicon Nitride. 
      • High fracture toughness. 
      • Can be polished to a surface roughness of Ra = 0.02um.  
      • Excellent mechanical properties.
