CERAMIC PROPPANT AND METHOD FOR PRODUCING SAME
First Claim
1. A method for producing a ceramic proppant, comprising the steps of:
- a) preparation, including grinding source materials, which contain magnesium-containing material, and auxiliary materials to produce a charge material;
b) granulating the charge material to produce proppant precursor granules; and
c) firing the proppant precursor granules to produce proppant granules, wherein the method comprises the step of pre-firing the magnesium-containing material in a reducing atmosphere.

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.
