Barium Zirconate, BaZrO₃

Barium Zirconate, BaZrO₃, is obtained by fusing zirconium oxide with barium hydroxide. After treatment with water and dilute acetic acid a fine greyish-white powder, easily soluble in hydrochloric acid, is obtained. Barium chloride may be used instead of the hydroxide.

By mixing solutions of barium chloride and potassium fluorzirconate a precipitate of composition 3BaF₂.2ZrF₄.2H₂O is obtained, but this may be either a compound or a mixture.
