Definition

Noun: A rare, polyvalent (having multiple valencies) metallic element belonging to the platinum group of metals. It is typically found in nature associated with platinum ores.

Usage

This term is the formal, scientific name for the chemical element with the symbol Ru. It is used primarily in technical, academic, and industrial contexts such as chemistry, materials science, and geology. * The catalyst's effectiveness is due to the presence of atomic number 44. * Atomic number 44 is extracted as a by-product of platinum refining.

Advanced Usage

• In Catalysis: The element is noted for its exceptional catalytic properties, often used in processes like hydrocarbon synthesis and hydrogenation.
  • The industrial process relies on a catalyst containing atomic number 44.
• In Alloys: It is used to harden platinum and palladium alloys for electrical contacts and wear-resistant materials.
  • The durability of the electrical contact is increased by an alloy of platinum and atomic number 44.

Variants and Related Words

• Ruthenium (Ru): The common name and chemical symbol for atomic number 44. This is the term most frequently used in both scientific and general contexts.
  • Ruthenium is a versatile catalyst.

Synonyms

• Ruthenium
