Jan 01, 2018 The reaction equilibrium of hydrothermal synthesis reaction shifts to the side of hydroxide or oxide when metallic salts are heated up. (53.1) MA x + xH 2 O = M (OH) x + xHA, M (OH) x = MO x 2 + x 2 H 2 O The method of synthesizing hydroxides or oxides making use of this shift of equilibrium is called the hydrothermal synthesis method.

Hydrothermal vents and the origins of life - Chemistry World

Most experts agree over ‘when’: 3.8–4 billion years ago. But there is still no consensus as to the environment that could have fostered this event. Since their discovery, deep sea hydrothermal vents have been suggested as the birthplace of life, particularly alkaline vents, like those found at ‘the Lost City’ field in the mid-Atlantic.

We simulated our hydrothermal synthesis reactor that had two inlets and one outlet. By considering nucleation and growth rate models, we obtained size distribution of particles prepared in the reactor. Calculated results indicated that the size distribution of obtained particles largely depended on the mixing of reactants and hot water.
