Abstract: A precursor composition for the production of granulated ceramic material to be used as hydraulic fracture proppant, comprises 20 to 55% pyroxene, and 15 to 50% olivine. The remaining component is quartz and/or feldspar. The precursor composition can be sintered in a broader temperature range. The resulting proppant material shows high mechanical strength and resistance to acids, and also higher stability under hydrothermal conditions than the prior art.

Abstract: A precursor composition for the production of granulated ceramic material, particularly for ceramic proppants, comprises 20 to 55% by weight of magnesium orthosilicate, 20 to 35% by weight of MgO, and 2.5 to 11% by weight of Fe2O3. The resulting lightweight proppant material shows high mechanical strength. To further decrease the specific density of the proppant, the formation of small pores can be increased by adding 0.3 to 2.4% carbon as a gas-forming agent.
