CERAMIC PROPPANT WITH LOW SPECIFIC WEIGHT

摘要

A precursor composition for the production of granulated ceramic material, particularly for ceramic proppants, comprises 20 to 55% by weight of magnesi um 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 smal l pores can be increased by adding 0.3 to 2.4% carbon as a gas-forming agent.< /SDOAB>
