Strontium
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.
To avoid oxygen contamination ESPI's strontium pieces and chips are manufactured in a dry argon environment. The finished pieces or chips are packaged for shipping in either sealed cans under dry argon, glass ampoules under dry argon, or sealed cans with a light coating of high purity mineral oil.
