Solid neutron star matter above the neutron-drip threshold has thermal fluctuations in nuclear charge, near the melting temperature, so large that the system probably cools to amorphous heterogeneous form rather than the homogeneous bcc lattice usually assumed. This result, obtained by the calculation of impurity nucleus formation enthalpy, shows the need to reconsider the electrical conductivity of neutron star matter, the evolution of the magnetic flux distribution, and the role of superfluid neutron vortex pinning in pulsar glitch phenomena.
