Description
The new type of insulation where metals, varistors on more in general media with a change in resistivity are called “smart insulation”. Among the latter, metal-to-insulator transition (MIT) materials have lately collected interest, since one could get both the advantage of a full insulation during charge/operation (low T) and hot-spot redistribution during a quench (high T).
In this respect, VxOy (Vandium Oxide) compounds were experimentally investigated. This study reports on their new off-stoichiometric chemical preparation, application process, resistivity ρ, effects of background field and thermal behavior between 4.2 K and 77 K.
