Description
Gallium is a rare chemical element with the atomic symbol Ga and the atomic number 31. It is located in the fourth period of the periodic table and is the third element of the third main group, the 13th IUPAC group or the boron group. It is a silver-white, easily molten metal. Gallium does not crystallise in any of the crystal structures commonly found in metals, but in its most stable modification, an orthorhombic structure with gallium dimers. Six other modifications are known to form under special crystallisation conditions or under high pressure. The chemical properties of the metal are very similar to those of aluminium.

* This is a recommendation based on our experience with these materials in our sputter guns. Rates are based on unbonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or less depending on the material.
