Nuclear grade product

Lithium-7 form cation, hydroxide form anion mixed bed

A 1:1 equivalent mixture of Gravex GR 7-16 NG (Li7) and GR 1-9 NG (OH)

Low residual chloride for nuclear applications

Unique mixing process insures the most accurate blend possible

Less separable product for non-regenerable application

Very high capacity product with excellent physical and chemical integrity & stability

Capacity allows the resin bed to remain in service beyond the typical one fuel cycle

Highly converted to the Li7 ionic form
