ABSTRACT:
The invention relates to a single phase vitreous material and to its production from a melt of a glass-forming multi-component feed mix. The process includes the preparation of a single phase melt in which there are mobile cations from a glass forming feed mix. The melt in passed in contacting relationship with and sequentially between devices made of low electrical resistance material from device to device. These devices are in and complete with the melt and a direct current voltage source an electric circuit. A voltage is regulated in the electrical circuit so that a direct electrical current is created in it and the concentration of the mobile cations in the melt is lowered thereby with reduction on the cathode of the metals of the same kind as the mobile cations. The melt, lowered concentration of the mobile cations, is cooled to produce the material as a structural article. In another embodiment, the anode is separated from the melt by a medium which is substantially inert with respect to the melt. A voltage in this electric circuit is regulated to create an electrostatic field between the cathode and anode so that a direct electrical current is created, and thus the concentration of mobile cations in the melt is lowered with reduction on the cathode of the metals of the same kind. This melt similarly is cooled to produce the material as a structural article. In another embodiment, the embodiments of both the electric circuit with the anode contacting with the melt and the electric circuit with the anode not contacting the melt are practiced simultaneously.
