Deposition of BaTiO3 Nanoparticles by Electrostatic Spray Powder Charging
In most models of ESC behavior, Pauthenier's equation is critical to the calculation of the maximum deposition thicknesses and to the spatial distribution of deposited particles.7-15 Today, the most common and widely accepted equation for modeling the charging of powders during electrostatic deposition is Pauthenier's equation. It is given by:
where m is the mass of the particle, E is the breakdown electric field of (E=3MV/m), e0 is the permittivity of free space, er is the dielectric constant of the powder, r is the bulk density of the material, r is the
particle radius.5
