 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 issues 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 .
