Specific weight of palladium, properties, applications and table
Palladium is a transition metal of the platinum group with a silvery-white color and good ductility. In nature, it occurs in ores and is often extracted during processing of sulfide ores of nickel, copper and other metals. Palladium is a precious metal widely used in industry, electronics, chemistry and jewelry.
Specific weight table for palladium
The exact specific weight of palladium depends on metal purity, temperature and sample condition. For reference calculations, a value of about 12.0 g/cm³ is usually used. This means that 1 m³ of palladium weighs approximately 12000 kg.
| Material | Specific weight, g/cm³ | Weight of 1 m³, kg |
| Palladium | 12.0 | 12000 |
Properties of palladium
Palladium has a face-centered cubic crystal lattice and good ductility. Small additions of other metals, such as nickel, cobalt, ruthenium or rhodium, can change mechanical properties, hardness and wear resistance of alloys.
The density of palladium is about 12.02 g/cm³ at 20 °C. Its melting point is about 1554 °C, and its boiling point is about 2940 °C.
Palladium does not dissolve in water and is resistant to many media, but it can react with nitric acid, halogens, aqua regia, sulfur and some concentrated acids. One important property of palladium is its ability to absorb and transmit hydrogen, which is used in technical processes.
Applications of palladium
Palladium is used in various areas of industry and technology. Main applications include:
- catalysts for chemical processes, oil refining, hydrogenation and exhaust gas treatment systems;
- hydrogen purification and separation due to hydrogen permeability through palladium;
- electroplating, including surface activation and metallization of dielectrics;
- electrical contacts and coatings resistant to corrosion and sulfide attack;
- precision resistive elements and components for special equipment;
- jewelry, including white gold alloys;
- chemical vessels and parts resistant to corrosion in certain environments.
Frequently Asked Questions
How much does 1 m³ of palladium weigh?
One cubic meter of palladium at a density of about 12.0 g/cm³ weighs roughly 12,000 kg. For precise calculations, use the density of the specific alloy or product.
Where is palladium used?
Palladium is used in catalysts, electronics, chemical equipment, hydrogen technologies and jewelry alloys. The application depends on metal purity and alloy composition.
Why can palladium density vary slightly?
Temperature, metal purity, alloying elements and sample condition affect the value. The reference density should therefore be used as a guide.
