tantalum in cell phones

How is tantalum used in phones? - SAM Sputter Targets

11/09/2018  A mobile phone has average 40 milligrams of tantalum inside. Well, compared with the total weight of a mobile phone, it is not a big number, but this 40 milligrams tantalum is irreplaceable. Due to the huge demand for mobile phones, the demand for tantalum has also increased. Believe it or not, about half the tantalum consumed each year is used within the electronics industry, 25% of
