Tantalio

1. TANTALO (Ta)

2. Anders Gustaf Ekeberg . Discovered in 1820. Maximum oxidation state on group 5. Hard, heavy and malleable. Transition metal. Greyish blue.

3. Metal shine. Corrosion resistant. High fusion point. Good electrical and heat conductor. Resistant at acids attacks. Dissolution  “ ácido fluorhídrico ”  “ fusión alcalina ”

4. Tántalo  Zeus’ son and Niobe’s father. Related to resistant at acids.

5. Fabrication of electrolytic condenser. Essential component of compact and electronic dispositive. Cause of change in chemist reactions. It’s extracted from tantalite. It appeared mixed with “ columbita ”  “ coltan ” 80% of global reserves.

6. IMPORTANCE OF RECYCLE: Important conductor. Located principally in Africa (Congo). It cause lot of exploitation. Getting 1 kilo 2/3 deaths Bad work conditions. 800 €
