Results from experimental studies of the formation of submicron particles during the destruction of solid bodies

详细

A procedure for and the results from studies on directly estimating the size and number of submicron particles at the moment of the destruction and disintegration of solid bodies are described. Experiments require the breaking up of metallic rods or the crushing of rock samples subjected to uniaxial compression, and continuous monitoring of the size of particles by laser spectrometry. The formation of submicron particles with minimum sizes of ∼0.1 μm is observed. The size distribution and number of these particles depend on the structural and physical parameters of the solid bodies.
