Superconducting carbon black is carbon powder that is prone to flying and causing pollution. However, the chemical properties of carbon black are very stable and not prone to chemical reactions. But why mention the shelf life of superconducting carbon black?
In fact, when stored under environmental conditions, superconducting carbon black is not easily affected by decomposition and its shelf life is not limited. However, over time, carbon black will absorb moisture, reducing its drying until it reaches equilibrium. This will result in the reuse of superconducting carbon black not achieving the same effect as before, or even being unusable at all. On this factor, the viewpoint of the shelf life of carbon black has been proposed, which is actually the preservation of carbon black. Normally, the shelf life of carbon black is one year.
So it is important to note that superconducting carbon black must be placed in a dry place. If the humidity is severe, it must be sealed properly, especially when the local rainy season arrives, and preparations should be made in this regard.
