This compares the properties of a Y-Ba-Cu-O high T/sub c/ conductor (T/sub c/ = 93 K) with niobium titanium (T/sub c/ = 9.4 K). If one assumes that the critical current density for the high T/sub c/ superconductor is the same as niobium titanium and they are both in a conducting matrix, one can make a direct comparison of the two types of superconductor. The comparisons in the paper include: adiabatic and dynamic stability diameter, normal region propagation rates, the burnout integral of J/sup 2/ dt, quench initiation energy, and matrix current density for cryogenic stability. From such a comparison, it is clear that high T/sub c/ superconductor may not be the superconductor of choice for many applications. An example of such an application is the use of high T/sub c/ conductors for accelerator magnets. 26 refs., 1 fig., 4 tabs.
