Abstract:
The invention relates to a method for producing a ceramic proppant, including a step for preparing an original charge material, involving the grinding of source materials, particularly magnesium-containing materials, and auxiliary materials, thus producing a charge material, granulating the charge material so as to produce granules of a proppant precursor, and firing the granules of proppant precursor, thus producing proppant granules, wherein the method includes a step for pre-firing the magnesium-containing material in a reducing atmosphere. The invention also relates to a ceramic proppant produced via the indicated method.

Claim (Index 15):
The method according to  claim 14 , characterized in that the auxiliary materials comprise quartz sand in an amount of 30 to 55 wt % of the charge material weight and clay in an amount from 0 to 10 wt % of the charge material weight.
