With thermal conductivity of 100 W/mK, Silicon Nitride serves as insulating substrate for power modules, high-frequency circuits, and LED mounting. High fracture toughness makes material resistant to impact and shocks. Product can be polished to surface roughness of Ra=0.02 µm and is wear-resistant. Supplied standard in sheet form measuring 100 x 100 mm with thickness of 0.32 mm, Silicon Nitride is also available as powder, rods, sheets, spheres, targets, and tubes.
