Strontium Sputtering Targets
Strontium is a chemical element with symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly reactive chemically. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, Calcium and Barium. It naturally exists in the minerals
Celestine, Strontianite, and Putnisite, and mined mostly from the first two of these.
While natural strontium is stable, the synthetic 90Sr isotope is radioactive and is one of the most dangerous components of nuclear fallout. The body similarly absorbs strontium as Calcium. Natural stable strontium, on the other hand, is not hazardous to health.
Strontium Sputtering Targets Information
Strontium Sputtering Targets
Purity: 99.5%;
Circular: Diameter <= 14 inch, Thickness >= 1mm;
Block: Length <= 32 inch, Width <= 12 inch, Thickness >= 1mm.
Due to these materials' highly reactive nature, packaging in oil is required to reduce the opportunity for oxidation or other reaction.
