The catastrophic disruption of interplanetary dust grains, including water-ice, obsidian and magnetite, by impinging solar cosmic rays is investigated. The disruption is caused by the stress wave emanating from the heated lattice atoms along the path of an impinging particle. We find that the disruption plays an important role in the mass loss rate of grains compared with that due to sublimation and sputtering by solar particles.
