Parameters of High Purity Superconductor Use Niobium Rod Niobium Bar Niobium Per Kg
The “Niobium Rod” and “Niobium Bar” refer to different forms of niobium used in superconductors. The “Per Kg Parameter” is likely referring to the concentration or purity of these niobium bars or rods, which can affect their performance as super conductors.
The concentration or purity of niobium bars or rods in a superconductor determines its critical temperature (Tc), which is the temperature at which the superconductor transitions from normal conducting state to a superconducting state without any resistance. A higher concentration of niobium in a bar or rod will result in a higher Tc.
It’s important to note that the exact value of the “Per Kg Parameter” would depend on the specific niobium bar or rod being referred to, as well as other factors such as the dimensions of the sample and the manufacturing process used to produce it.
