摘要:
Disclosed herein is a coated particle comprising a substrate comprising an inorganic material, wherein the inorganic material comprises silica and alumina in a silica to alumina weight ratio of about 2.2 to about 5; and wherein the inorganic material has a bulk density of less than or equal to about 1 g/cm3; and a coating disposed upon the substrate. Disclosed herein too is a method of treating a subterranean formation comprising injecting a fracturing fluid into the subterranean formation; wherein the fracturing fluid comprises an inorganic particle that comprises silica and alumina in a silica to alumina weight ratio of about 2.2 to about 5; and wherein the inorganic particle has a bulk density of less than or equal to about 1 g/cm3.
