Reaction Steps
A filtered solution of barium hydroxide octahydrate reacted with an aqueous solution of boric acid to provide hydrated γ barium borate having a barium to boron ratio of 1:2 and having fine particle size. The hydrated γ barium borate was converted to the anhydrous γ form at about 300° to 400° C. Further heating to about 600° to 800° C. converted the product to β-BaB2O4. The conversion to the β-form is preferably during sintering of a ceramic dielectric composition to which the γ-BaB2O4 has been added as a flux.
