Electrochemical behavior of the catalyst with kaolinite-bentonite substrate in water

Due to the fact that oxidation-reduction potential and rH2 value of every water are its crucial features, numerous efforts have been made to use electrochemical means for water preparation. In this paper, we report the results of electrochemical influence research of magnesium-aluminium silicate catalyst, in the form of ceramics made of kaolinite and bentonite clays, on the rH2, pH and EOR changes of the waters of particular characteristics in the wanted direction. Particularly, the possibility of changing "active water" characteristics was investigated. The composite made with micro alloyed aluminium exhibits a very negative stationary potential and its interaction with water results in water reduction. Addition of some active components to the mixture of kaolin and bentonite can provide clay mixtures, which after sintering at high temperatures produce very porous ceramics with microcrystalline and amorphous regions of stoichiometric and nonstoichiometric new oxides and some metallized surface (in our case-mainly with magnesium surplus). Nonstoichiometric oxide mixtures and metallized amorphous ceramics regions show high electrochemical and chemical activities in contact with water. This leads to redox potential changes and appearance of Mg2+ ions in the magnesium aluminium silicate-water system
