STRONTIUM
(Sr)
MATERIAL
OVERVIEW
Characteristics:
Pale yellow, soft metal, chemically similar to
calcium. Soluble in alcohol and acids; decomposes
water on contact. Low toxicity.
Hazards:
Spontaneously flammable in powder form, ignites when
heated above melting point. Reacts with water to
evolve hydrogen. Store under mineral oil or argon.
