Bariumzirconiumtrioxid Chemische Eigenschaften,Einsatz,Produktion Methoden

R-S?tze Betriebsanweisung:

R20/22:Gesundheitssch?dlich beim Einatmen und Verschlucken.

S-S?tze Betriebsanweisung:

S28:Bei Berührung mit der Haut sofort abwaschen mit viel . . . (vom Hersteller anzugeben).

Chemische Eigenschaften

Light gray-buff powder. Insoluble in water and alkalies; slightly soluble in acid.

Verwenden

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.

Sicherheitsprofil

Moderately toxic by ingestion and intraperitoneal routes. Inhalation produces interstitial pneumonitis. See also ZIRCONIUM COMPOUNDS and BARIUM COMPOUNDS.
