An aqueous boric acid dispersion includes boric acid particles having a median particle size range of less than 44 microns and a solids content of boric acid particles of 50% or greater. The boric acid dispersion also includes an effective amount of at least one viscosity reducing agent such that the boric acid dispersion has an initial Brookfield 2 rpm static viscosity of about 5,000 to about 25,000 centipoise and a three week aged Brookfield 2 rpm static viscosity of less than 250,000 centipoise, an optional amount of an alkali metal base, wherein the alkali metal base/boric acid mole ratio in the boric acid dispersion ranges from zero to about 0.01; and the balance water. The boric acid dispersion can be used in the manufacture of wood products like oriented strand board, medium density fiberboard, and particle board as well as to coat wood products to improve their fire retardancy.
