Abstract
Microgravity experiments on the order formation of silica particles under the critical concentration for colloidal crystallization were planned and prepared. Optical system was constructed for the following three experiments; (i) voids detection by measuring intensity of transmitted-light run through dispersions, (ii) observation of individual particles with diameters of 1.0 and 3.0 μm at lower concentration than 1.0 vol% by an optical microscope and (iii) position identification and size estimation of larger grains of colloidal crystals by an ultramicroscope with ring light source consisted of LEDs of different wavelengths.
