Use of uncalcined/partially calcined ingredients in the manufacture of sintered pellets useful for gas and oil well proppants
Patent
·
OSTI ID:6954733
This patent describes a composite, sintered, spherical pellet suitable for gas and oil well proppant which is prepared from materials consisting essentially of clay materials, bauxitic materials and alumina. The materials include at least one uncalcined or partially calcined ingredient selected from the group consisting of clay materials, bauxitic materials and dust collector fines produced during the calcination of clay materials and bauxitic materials, and alumina. The pellet has on a dry weight basis an alumina-to-silica ratio from about 9:1 to about 1:1 and at least about 6.51 percent by weight of other than alumina and silica, the pellet having an apparent specific gravity of less than 3.30.
