FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly to dispersion of nano-sized silicon dioxide powder in fluid. It can be used as a modifying agent for paint-and-lacquer materials, concretes, and adhesives for tile paving. Fluid containing Tarcosil T05B06-grade silicon dioxide powder is subjected to ultrasound vibrations of dispersant. Said vibrations are maintained for three minutes in sound cavitation medium on resonance frequency of about 23 kHz.
EFFECT: homogeneous mix resisting the demixing.
