Boron combines with oxygen and other elements to form boric acid or inorganic salts called borates. Boron compounds, chiefly borates, are commercially important; therefore, boron products are priced and sold based on their boric oxide (B 2 O 3) content, varying by ore and compound and by the absence or presence of calcium and sodium.
