What is Barium zirconate?
Chemical properties
Light gray-buff powder. Insoluble in water and alkalies; slightly soluble in acid.
The Uses of Barium zirconate
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.
The Uses of Barium zirconate
Manufacture of a white, easily colored silicone rubber compound having good heat stability at temperatures up to 500F; electronics.
Flammability and Explosibility
Not classified
Safety Profile
Moderately toxic by ingestion and intraperitoneal routes. Inhalation produces interstitial pneumonitis. See also ZIRCONIUM COMPOUNDS and BARIUM COMPOUNDS.
