Platinum metal (Pt)-Crucible

Platinum metal (Pt)-Crucible introduce:

Characteristic




Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. 




Phase at STP: solid

Melting point: 2041.4 K (1768.3 °C, 3214.9 °F)

Boiling point: 4098 K (3825 °C, 6917 °F)

Density (near r.t.): 21.45 g/cm3

when liquid (at m.p.): 19.77 g/cm3

Heat of fusion: 22.17 kJ/mol

Heat of vaporization: 510 kJ/mol

Molar heat capacity: 25.86 J/(mol·K)




Application




Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Being a heavy metal, it leads to health problems upon exposure to its salts; but due to its corrosion resistance, metallic platinum has not been linked to adverse health effects. Compounds containing platinum, such as cisplatin, oxaliplatin and carboplatin, are applied in chemotherapy against certain types of cancer.
