Beschreibung
Zusammenfassung:	This invention relates to the oil and gas production industry and can be used for preventing fracture closing during fracturing of producing oil layers. Proppant comprising baked feedstock grains, with the difference that a burden material comprising silicon oxide and aluminum oxide at the aluminum oxide content of not less than 60% (by weight) is used as the feedstock; the apparent density of the proppant varies from 1.7 to 2.75 g/cm3
