ABSTRACT:
A process is provided to prepare solid borozirconate and solid borotitanate cross-linkers, which comprises contacting zirconium or titanium complex with alkanolamine at particular mole ratios of boron, zirconium or titanium and alkanolamine. Use of the cross-linkers in compositions for oil field applications such as hydraulic fracturing and plugging of permeable zones are also disclosed.
