Reactivity Alerts: 

Strong Reducing Agent

Reactivity Profile: 

YTTRIUM in bulk is stable in air due to the formation of oxide films. Powder or dust is light-sensitive and air-sensitive and flammable in the air and (Hazardous Chemicals Desk Reference, p. 861 (1987)). Reacts with water to form gaseous hydrogen (H2). Reacts with strong oxidizing agents, strong acids, strong bases, and halogens. The products of these reactions are irritating and toxic.

Flammable Limits: 

Noncombustible Solid in bulk form.
