A superconductive model characterized by a third order parabolic operator ${\mathcal L}_\varepsilon$ is analyzed. When the viscous terms, represented by higher-order derivatives, tend to zero, a hyperbolic operator ${\mathcal L}_0$ appears. Furthermore, if ${\mathcal P}_\varepsilon$ is the Dirichlet initial-boundary value problem for ${\mathcal L}_\varepsilon$, when ${\mathcal L} _\varepsilon$ turns into ${\mathcal L}_0 ,$ ${\mathcal P}_\varepsilon$ turns into a problem ${\mathcal P}_0$ with the same initial-boundary conditions of ${\mathcal P}_\varepsilon$. As long as the higher-order derivatives of the solution of ${\mathcal P}_0$ are bounded, an estimate of solution for the nonlinear problem related to the remainder term $r,$ is achieved. Moreover, some classes of explicit solutions related to ${\mathcal P}_0$ are determined, proving the existence of at least one motion whose derivatives are bounded. The estimate shows that the diffusion effects are bounded even when time tends to infinity.
