A chemist examines a silicide sample under bright laboratory lights.

Definition

Noun: 1. A binary compound of silicon with a more electropositive element or radical: A silicide is a chemical compound in which silicon is bonded to a more electropositive element, typically a metal. These compounds are often hard, refractory materials with high melting points and are significant in materials science and semiconductor technology.

Usage Examples

• Noun:
  • Magnesium silicide is used in some pyrotechnic applications.
  • The formation of a tungsten silicide layer is a critical step in microchip fabrication.
  • Calcium silicide can react with water to produce silane gas.

Advanced Usage

• In Materials Science: The term is frequently used to describe specific, engineered compounds with precise stoichiometries (e.g., platinum silicide, PtSi).
  • The interface between the silicon wafer and the metal contact was stabilized by creating a thin titanium silicide layer.
• As a Class of Materials: Used to refer to the entire group of such compounds collectively.
  • Transition metal silicides are studied for their potential in thermoelectric devices.

Variants and Related Words

• Silicon (n): The chemical element (Si) that is a component of all silicides.
• Disilicide (n): A specific type of silicide containing two silicon atoms per formula unit (e.g., molybdenum disilicide, MoSi₂).
• Monosilicide (n): A silicide containing one silicon atom per formula unit (e.g., iron monosilicide, FeSi).

Synonyms

• Silicon compound: A broader term that includes silicides as well as other compounds like silicates or silicon oxides.
• Binary silicon compound: A more technical term specifying a compound containing only silicon and one other element.
