Palladium - Pd

It is a precious metal with the appearance of steel and does not change color when exposed to air. In the annealed state, it is soft and ductile. Cold working significantly increases its hardness and strength. It is attacked by sulfuric and nitric acids.

Main uses:
  • Catalytic converters for internal combustion engines
  • Carbon monoxide detectors
  • Jewelry
  • Catalyst for hydrogenation and dehydrogenation reactions
  • Dental
  • Watchmaking
  • Surgical instruments
  • Electrical contacts
Properties:
  • Atomic Weight: 106.42
  • Specific Gravity: 12 (20ºC)
  • Melting Point: 1555ºC
  • Boiling Point: 2963ºC

Platinum - Pt

It is a noble metal with a silvery-white appearance. In its pure state, it is malleable and ductile. It is not oxidized by air at any temperature but is corroded by halogens, cyanides, sulfur, and alkalis. It is not affected by hydrochloric and nitric acids individually but is attacked when mixed (aqua regia).

Main uses:
  • Jewelry
  • Furnace resistors
  • Laboratory vessels
  • Instruments like thermocouples
  • Electrical contacts
  • Dental
  • Glass-to-metal seals
  • High-capacity magnets
  • Catalyst in sulfuric acid production
  • Petroleum derivatives
  • Fuel cell catalysts
  • Cathodic protection
Properties:
  • Atomic Weight: 195.08
  • Specific Gravity: 21.45 (20ºC)
  • Melting Point: 1768ºC
  • Boiling Point: 3825ºC
