“…These charged particles electrostatically repel one another and the system minimizes its free energy (2,(20)(21)(22)(23) by self-assembling into either a body-centered cubic (BCC) or face-centered cubic (FCC) lattice (24)(25)(26).…”

“…Crystals of the same type of phases (supercrystals) have already been shown to exist in two symmetry classes; those of the tobacco mosaic virus are hexagonal (Oster, 1950), and those of the Tipula iridescent virus (Klug, Franklin & Humphreys-Owen, 1959) and of monodisperse high polymer suspensions (Luck, Klier & Wesslau, 1963) are cubic. In the two latter cases the crystal lattice is equivalent to the dense packing of spheres [space group Fm3m (O~)].…”

Two examples have been observed of an orthorhombic crystal type, composed of particles of dimensions about 10--6 to 10 -4 cm separated by water layers of the same order of magnitude. The particles themselves are small crystals, likewise of orthorhombic shape, at least to a first approximation. Like the cubic crystals of certain viruses and similar systems, they belong to the same type of phase as the smectic and nematic 'tactosols' and the amorphous 'coacervates'.In order to distinguish phases of this type from those composed of molecules in immediate contact, they might be named phases of higher order or superphases. Their equilibrium is mainly determined by the surface charges and their counterions. The influence of temperature is small. Such phases with translation periods (smectic or crystalline) exhibit iridescence instead of X-ray interference.The new orthorhombic crystals are obtained from the iridescent smectic tactosols of ferric chloride hydrolysate and of tungstic acid by a treatment that diminishes the distance between the particles. In the smectic state the crystal leaflets are distributed at random around the main axis. They reveal their orthorhombic oblong shape only at short distance in the supercrystals by arrangement in a threedimensional periodic lattice.

“…However, when the structures of charged latex particles dispersed in water. Luck et al (26) and Kose et al (27) demonstrated (using the ionic strength is moderately high, 1.03 £ kd £ 2.79, the result for the potential of mean force between ion i and j in microscope) the formation of the hexagonal packing structure. Having noticed and analyzed the phase transition and a solution can be expressed as phase coexistence phenomena, Takano and Hashisu (28) …”
