    摘要: A process for the preparation of hydrolytically and hydrothermally stable consolidated proppants is described, in which (A) a consolidating agent comprising (A1) a hydrolysate or precondensate of at least one functionalized organosilane, a further hydrolyzable silane and at least one metal compound, the molar ratio of silicon compounds used to metal compounds used being in the range of 10 000:1 to 10:1, and (A2) an organic crosslinking agent are mixed with a proppant and (B) the consolidating agent is cured at elevated pressure and elevated temperature.The consolidated proppants obtained have high mechanical strength.
