1. A method of reducing the presence of particles in a downhole environment, comprising:
contacting sediment particles contained in a downhole environment, with
a composition comprising:
a metallic composition,an inorganic oxide-based polymer, the inorganic oxide-based polymer comprising a plurality of structural repeating units which comprise —(X—O)— where X is Si, Al, P, or a combination comprising at least one of the foregoing, and the inorganic oxide-based polymer having a number averaged particle size of about 5 nm to about 10 mm; anda solvent; the contacting occurring in the presence of a fluid capable of decomposing the metallic composition; wherein the metallic composition comprises magnesium alloy particles coated with one or more layers to adjust the decomposition rate of the magnesium alloy in the fluid, wherein the magnesium alloy particles comprise magnesium having a valence of zero alloyed with aluminum, cadmium, calcium, cobalt, copper, iron, lithium, manganese, nickel, potassium, silver, sodium, strontium, thorium, tin, titanium, tungsten, zinc, zirconium, or a combination comprising at least one of the foregoing; and wherein the magnesium alloy particles have a corrosion rate of about 0.1 to about 200 mg/cm2/hour determined in aqueous 3 wt % KCl solution at 200° F. |
