The gel method of crystal growth is a rather simple technique for the controlled crystallization of certain compounds.1 Single crystals of CsSn2I5 have been grown in sodium metasilicate gels and identified by X-ray powder and single crystal diffracti

Single crystals of several rubidium and cesium tin halides of up 3 × 3 × 3 mm have been grown in sodium metasilicate gels and identified by X-ray powder and single crystal diffraction methods and by chemical analyses. Several different crystal habi

Differential thermal analysis measurements on Na 0.8 WO 3 crystals, run between 300 and 770°K, indicate sample heat capacity changes near 420 and 730°K. Specific heat changes for Na 0.8 WO 3 were found near these same temperatures, with values rang

Conditions for single crystal growth of pure and doped sodium tungsten bronzes have been investigated. In all cases visual observation of the melt was very helpful. With doped crystals, the impurity concentration in the melt and the preparation tempe

Sodium tungsten bronze crystals of composition Na 0.8 WO 3 were doped with varying concentrations of Nb and Ta. The cubic perovskite crystal structure typical of sodium bronzes was found for all samples containing less than about 10% Nb or Ta; lattic

Single crystals of the sodium tungsten bronzes with simple cubic habits and dimensions of about 1 × 1 × 1 cm have been grown by an eloctrylytic adaptation of the Kyropoulos technique.
