gas the following calculations show the surface areas present for a single bubble a plurality of one inch diameter bubbles and a plurality of 50 micron diameter bubbles wherein each calculation is based on one cubic foot of gas the aggregate surface area for a dispersion of gas increases markedly as the radius of the bubbles decreases for instance a dispersion of 50 micron diameter bubbles containing one cubic foot of gas will have an aggregate surface area that is more than 500 times greater than a dispersion of one inch bubbles containing the same volume of gas one novel aspect of this invention involves the substitution of a newtonian solvent with a bingham plastic such a material requires a finite yield stress to initiate movement applied stress levels that are below the yield stress threshold will not result in movement of the fluid a bingham plastic can be considered to have infinite viscosity and behave as a solid at stress levels below the yield stress a bingham plastic should result in bubble immobilization provided that the magnitude of the buoyancy forces exerts a stress level that falls below the yield stress for the bingham plastic bubble immobilization would thus provide stability of the micro bubble suspension it has been discovered that the current invention produces stable suspensions of micro bubbles when a bingham plastic is used as the matrix this is preferably accomplished by adding and mixing ingredients to form a bingham plastic and oxygenated liquid at elevated pressure i e prior to the formation.
