Description	High-energetic water jet (at cross-sectional velocity exceeding 660 ms(-1)) represents a liquid flow with cross-sectional power density about/or above 144 kWmm(-2). In the experimental Water Jet Mill (WJM) device, potent dynamics of disintegration of silicon microparticles develop during the passage of modified cavitation water jet through the microparticle dispersion. The main mechanism of this disintegration of solid microparticles is the extreme impact pressure of a water-hammer on particle surface in the termination phase of the implosion of vapor cavitation bubbles. Around the working temperature of WJM about 65 degrees C, cavitation erosion of solid materials in water reaches high intensity. Gradients of flow velocity in the disintegration zones of WJM rise up to 1000 ms(-1)/mm and generate markedly high tensile stresses in the liquid, resulting in the creation of vapor cavitation bubbles. The cavitation coefficient reaches values of 10(-4) rank and the cavitation intensity is very high.
