Gallium Metal

Gallium metal is magnetic and an excellent conductor of both heat and electricity. It expands on solidifying (by 3.2%) and the density is higher in the liquid than in the solid state. It’s melting point is only 29.8°C and easy to become to liquid form at Summer. Santech is engaged in re-processing of Gallium and dedicates most of R&D efforts to its granules, alloys and compounds, which are widely used in photovoltaic cells and LED industries.
