The most important features of Silicon Nitride is that Silicon Nitride does not react with molten aluminum and has non-wetting properties to molten aluminum. Our Silicon Nitride Tube has a very good thermal conductivity which is important to transfer heat effectively from the heater to molten aluminum.
