| | Barium zirconate Usage And Synthesis |
| Chemical Properties | Light gray-buff powder. Insoluble in water and alkalies; slightly soluble in acid. | | Uses | Manufacture of a white, easily colored silicone rubber compound having good heat stability at temperatures up to 500F; electronics. | | Uses | Barium zirconium oxide is involved in the preparation of its nano powder, which finds application in the gas sensing performance of thick films especially with ammonia gas. Copper(II) oxide doping with yttrium-doped barium zirconate is used as an electrolyte in solid oxide fuel cell. | | Flammability and Explosibility | Not classified | | Safety Profile | Moderately toxic by
ingestion and intraperitoneal routes.
Inhalation produces interstitial pneumonitis.
