The viability of utilizing salt-inclusion materials (SIMs) as a hierarchical wasteform has resulted in the successful synthetic preparation of a variety of SIMs with uranium-containing frameworks which incorporate oxoanion groups, including silicates and germanates. Considering the pervasive role of the borate anion in current nuclear waste storage processes, it is a logical extension of the currently existing uranium SIMs to investigate the synthetic conditions in which a uranium borate SIM could be prepared. The high temperature flux method has thus far shown to be the prevailing growth technique for SIMs in general, while broader uranium borate crystal chemistry has primarily been dominated by the mild hydrothermal method. This talk will focus on the synthetic techniques employed to synthesize porous uranium borates, in order to ultimately develop a targeted synthesis route to the first uranium borate salt-inclusion material.
