Activated Deposition of Aluminum Silicate Film at Granite-Dry Steam Interaction

We have observed that a highly protective amorphous aluminum silicate layer on a steel surface was formed after granite–dry steam interaction in the presence of a copper plate near the critical point of water. In this process, the mass transfer of aluminum and silicon species from the granite to the steel surface takes place after copper was transferred to the granite surface. The rate of this process is accelerated by the presence of copper on the granite surface. At present, we have determined the effect of transferred copper species on the weight loss of granite in dry steam with different ratios of O2 and N2. It was also found that transferred copper species at a low O2 level promote the weight loss of granite. Four types of experiments were conducted at low O2 ratios in different‐density steam: (1) steel–steam, (2) steel–Cu–steam, (3) steel–granite–steam, and (4) steel–granite–Cu–steam. It was established that an aluminum silicate film formed on the steel surface only at the steel–granite–Cu–dry steam interaction. The formed film was characterized by scanning electron microscopy equipped with energy‐dispersive X‐ray spectroscopy and by X‐ray photoelectron spectroscopy. (© 2006 WILEY‐VCH Verlag GmbH & Co.

In this paper, it is demonstrated how information obtained from the study of fundamental Earth principles can be used to inspire the development of new methods for material recycling, such as the following: 1) Hydro thermal hotpressing processes, simulating the formation of sedimentary rock sequences, can be used for the solidication of toxic and hazardous materials. 2) Organic materials could be formed from CO 2 under hydrothermal conditions (using Fe and Ni metals, and low valence Fe oxides), at temperature and pressure conditions consistent with a subduction (tectonic) setting, such as (under Japan) where the Pacic Plate sinks beneath the (Eurasian) continental plate. 3) Diamondstructured carbon may be formed from toxic chlorinated hydrocarbon, in very high pressure regions of the Earth, and at high alkaline hydrothermal con ditions, where magma formation may occur. 4) High temperature dry steam in rock fractures (at near criti cal conditions \i.e. below saturated vapor pressure, but relatively high pressure) is not only a source/carri er of noble metals, including gold, silver and copper, but also ceramic materials, silica and alumina. Its laboratory simulation may also be a guide for the formation of thin layer silicate ceramics on metal plates (e.g. SUS304 nickel alloy). 5) To design an underground boiler in hot dry rock, nonequilibrium dissolution and deposition hydrothermal processes may be studied using a tube reactor, which simulates uid ow and temperature gradients in fractured hot rock.
