内容: 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 FeZO3. 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.
