We evaluated the growth and dissolution behavior of the primary α phase, Sr(NO3)2, and peritectic β phase, Sr(NO3)2·4H2O, coexisting in aqueous solutions above or below the peritectic temperature (Tp) in situ. Above Tp, when the two phases simulta

Alkali metals (Na, Rb or Cs) co-doped with fiber- and bulk-shaped KNbO3 single crystals were grown using two original methods by means of doping together of small ionic Na and large ionic Rb or Cs into KNbO3. Single-phase crystals could be grown with

Method to synthesize KNbO3 crystals using K2NbO3F solutions is of interest. In this paper, films of KNbO3 crystals are synthesized on several oxide substrates from K2NbO3F solutions. The films have some orientation due to a reaction with the substrat

Ytterbium garnet and holmium garnet single crystals are of interest from the viewpoint of magnetic frustrations in the low-temperature region. Reports on the magnetic frustrations of these single crystals are rare, since it is difficult to grow them.

Bismuth titanate (Bi4Ti3O12) crystals were grown by our original floating-zone pulling down (Fz-PD) method. The shape of the grown crystals was fiberlike with dimensions of 15×1×0.34 mm3. The dielectric properties and impedance of the grown fiber c

KNbO3 crystal is an incongruent melting crystal from a peritectic system. At first, a crystal was formed from the molten zone center of the stoichiometric composition using our original modified floating zone technique. Then the crystal was grown con

The normal growth rate R , hillock slope p and step velocity v = R / p of spiral growth hillocks on the (1 1 1) face of a Sr(NO 3 ) 2 crystal growing in aqueous solutions were measured as a function of supersaturation σ for various growth temperatur
