METHOD FOR COMMINUTION OF A MATERIAL

摘要

A method for comminution of a material including: submerging the material in water and applying a high voltage discharge to the material, said high voltage discharge being applied at a voltage and energy sufficient to form cracks at grain boundaries within the material, thereby weakening the material at said grain boundaries; treating the material with salt water such that salt water is deposited in said cracks at the grain boundaries within the material; and applying electromagnetic radiation to the material, thereby fracturing the material along said grain boundaries.
