Van Der Waals Forces & Static Electricity

When friction is applied in a ball mill, that is literally a recipe for binding two substances together with static electricity. But something else also happens to the fumed silica inside the ball mill: The fragile strands of nano-spheres are crushed and broken into tiny pieces. The resulting tiny pieces are considerably smaller than a spore.
