ABSTRACT:
Disclosed is the compound trihydrated potassium triborate having the following chemical formula: KB.sub.3 O.sub.5.3H.sub.2 O. Also disclosed is a process for the production of trihydrated potassium triborate by reacting potassium pentaborate tetrahydrate with either dipotassium tetraborate tetrahydrate or with dipotassium pentaborate pentahydrate by contacting the two solid reactants under reaction conditions including an amount of water sufficient to cause reaction and insufficient to dissolve the two reactant solids. The new trihydrated potassium triborate may also be prepared by treating dipotassium pentaborate pentahydrate with water under the same reaction conditions.
