in USA since 1960 as a broad-spectrum bactericide and
fungicide. It is added to paints, coatings, adhesives, plastics,
and paper and paper products.
Preparation
Barium metaborate
can be prepared by reactionof an aqueous solutionof boric
acid with Ba(OH)2. The prepared g-BBO contains water of
crystallization that cannot be completely removed by
drying at 120 °C. Dehydrated g-BBO can be prepared
by heating to 300–400 °C.
Flammability and Explosibility
Non flammable
Toxics Screening Level
