<p>A mechanical impact force is applied to bristle ultra fine particles supplied to a substrate to break the particles and bond together the particles or to bond together the particles and the particles and the substrate. The mechanical impact force to be applied to the ultra fine particles supplied to the substrate is realized: by accelerating the bristle ultra fine particles by applying an electrostatic field or by using gas carrier to blow them to the substrate; by using a high rigidity brush or roller (13) rotating at high speed, pressure needles moving up and down, or a piston moving at high speed utilizing explosion compression force; or by using ultrasonic waves. The pre-processing is by adjustment by changing a pre-sintering temperature of the bristle ultra fine particles, through formation of secondary cohesive particles of about 50 to 5 microns in diameter by heating the particles of several tens nm or smaller in diameter. Alternatively, forming the particles with cracks using a ball mill and a jet mill.</p> |
