Calcium’s primary commercial application is as a reducing agent in the production of other metals. In iron and steel production it is added to the melt to remove oxygen, sulfur and carbon. Calcium is also used in small doses in alloys of copper and beryllium. Various calcium compounds have wide application in food, pharmaceutical and cosmetics. It is also used in dietary supplements because it has been shown to improve bone and dental health. Calcium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity). Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Calcium is also available in soluble forms including chlorides, nitrates and acetates. These compounds can be manufactured as solutions at specified stoichiometries.
Our Calcium Sputtering Target is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
SAM specializes in producing high purity Calcium Sputtering Target with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications.

We use such a target to load single atoms into an ion trap via laser ablation inside a UHV chamber. The calcium sputtering target worked well.
I got the sputtering targets and they are fantastic. Worked perfect for my craft project and I would definitely buy them again
