Method for heat treating and sintering metal oxides with microwave radiation

Patent Holcombe, Cressie E [Farragut, TN]; Dykes, Norman L [Oak Ridge, TN]; Meek, Thomas T [Knoxville, TN]

A method for microwave sintering materials, primarily metal oxides, is described. Metal oxides do not normally absorb microwave radiation at temperatures ranging from about room temperature to several hundred degrees centrigrade are sintered with microwave radiation without the use of the heretofore required sintering aids. This sintering is achieved by enclosing a compact of the oxide material in a housing or capsule formed of a oxide which has microwave coupling properties at room temprature up to at least the microwave coupling temperature of the oxide material forming the compact. The heating of the housing effects the initial heating of themore » « less

Thermal insulation for high temperature microwave sintering operations and method thereof

Patent Holcombe, Cressie E [Knoxville, TN]; Dykes, Norman L [Oak Ridge, TN]; Morrow, Marvin S [Kingston, TN]

Superior microwave transparent thermal insulations for high temperature microwave sintering operations were prepared. One embodiment of the thermal insulation comprises granules of boron nitride coated with a very thin layer of glassy carbon made by preparing a glassy carbon precursor and blending it with boron nitride powder to form a mixture. The blended mixture is granulated to form a grit which is dried and heated to form the granules of boron nitride coated with a glassy carbon. Alternatively, grains of glassy carbon are coated with boron nitride by blending a mixture of a slurry comprising boron nitride, boric acid binder,more » « less

Method for digesting spent ion exchange resins and recovering actinides therefrom using microwave radiation

Patent Maxwell, III, Sherrod L. (Aiken, SC); Nichols, Sheldon T [Augusta, GA]

The present invention relates to methods for digesting diphosphonic acid substituted cation exchange resins that have become loaded with actinides, rare earth metals, or heavy metals, in a way that allows for downstream chromatographic analysis of the adsorbed species without damage to or inadequate elution from the downstream chromatographic resins. The methods of the present invention involve contacting the loaded diphosphonic acid resin with concentrated oxidizing acid in a closed vessel, and irradiating this mixture with microwave radiation. This efficiently increases the temperature of the mixture to a level suitable for digestion of the resin without the use of dehydratingmore » « less

Method and apparatus utilizing ionizing and microwave radiation for saturation determination of water, oil and a gas in a core sample

Patent Maerefat, Nicida L [Sugar Land, TX]; Parmeswar, Ravi [Marlton, NJ]; Brinkmeyer, Alan D [Tulsa, OK]; ...

A system for determining the relative permeabilities of gas, water and oil in a core sample has a microwave emitter/detector subsystem and an X-ray emitter/detector subsystem. A core holder positions the core sample between microwave absorbers which prevent diffracted microwaves from reaching a microwave detector where they would reduce the signal-to-noise ratio of the microwave measurements. The microwave emitter/detector subsystem and the X-ray emitter/detector subsystem each have linear calibration characteristics, allowing one subsystem to be calibrated with respect to the other subsystem. The dynamic range of microwave measurements is extended through the use of adjustable attenuators. This also facilitates themore » « less
