Abstract
Compositions formed in accordance with a method of controllably altering the mineral matter transformation of mineral compositions such as, for example, vermiculitic micas, to achieve metamorphosed mineral compositions having specifically desired monatomic lattice defects are provided that exhibit physical properties desirable in a variety of industrial applications, including, for example, control and/or reduction of NOx, SOx, COx and other gaseous chemical species from industrial effluents, atmospheric control systems, fabrication and use of chemical detectors, and solid state electronic substrates and devices.
Claims22
A system for controlling and/or reducing one or more undesirable gaseous components in an exhaust gas comprising:
- a reaction vessel;
- and
- an amount of a metamorphosed mineral composition,
- wherein said reaction vessel adapted to create a contact surface between an exhaust gas and at least a portion of said amount of said metamorphosed mineral composition, and wherein said metamorphosed mineral composition comprises up to about 50% by weight of a scavenger material, up to about 95% by weight of a mineral composition, and an effective number of monatomic defects in the crystal lattice.
A device for detecting the presence of chemical species in a gaseous environment comprising a sensor device including a metamorphosed mineral composition comprising:
- up to about 50% by weight of a scavenger material,
- up to about 95% by weight of a mineral composition;
- an effective number of monatomic defects in the crystal lattice.
A personal breathing apparatus including a metamorphosed mineral composition comprising:
- up to about 50% by weight of a scavenger material,
- up to about 95% by weight of a mineral composition;
- an effective number of monatomic defects in the crystal lattice.
