Abstract
The present invention relates to novel microporous zirconium silicate compositions having a desired particle size distribution and methods of making those compositions. These compositions have an ideal particle size distribution for use ex vivo, for example in a dialysis exchange cartridge, yet retain many of the desirable properties of prior improved absorbers including high cation exchange capacity. Further, the new zirconium silicate molecular sieve absorbers can be manufactured using a technique that achieves the desired particle size distribution while eliminating the screening step that was previously necessary.
