Hydrothermal synthesis of gallium orthophosphate crystals
Journal of Crystal Growth, 1986Some orthophosphates are known to have polymorphism similar to SiO2. The low temperature form of gallium phosphate, GapO4, is especially attractive due to its electrical character superior to α-quartz. In the present work, single crystals of GaPO4 have been grown hydrothermally at temperatures below 400 °C in phosphoric acid solution. Highly pure GaPO4

Hydrothermal Synthesis of Bismuth Titanate Powders
Journal of the American Ceramic Society, 2003Bismuth titanate was synthesized under hydrothermal conditions from an amorphous bismuth–titanium precursor gel. The gel was formed by mixing a bismuth acetate complex with titanium butoxide and then adding the solution dropwise into 6 M NaOH.

Hydrothermal Synthesis of Germanates
1973The limits of phase formation and crystallization in the Na2O-ZnO-GeO2-H2O system at high temperatures and pressures was discussed earlier [1]. The fundamental possibility of synthesizing germanates of various compositions under hydrothermal conditions was clearly indicated.

Hydrothermal Zeolite Synthesis
1989The diversity of structure among the zeolite frameworks surpasses that of other three-dimensional networks with 60 different topologies and numerous variations within a given topology. The number of possible novel zeolites thus is great. Today, over 150 zeolite structures have been synthesized, some of them counterparts to the naturally occurring ...

Hydrothermal synthesis of beidellites
Low-charge beidellites were synthesized by a hydrothermal treatment applied to an amorphous gel phase in basic solution. The hydrothermal conditions for the syntheses were chosen from the stability field of beidellite previously investigated in the literature. The synthetic samples were characterized chemically and structurally using X-ray diffraction,Lantenois, Sébastien +4 more
