A scientist examines a silicate mineral under bright laboratory lights.

Definition

1. Noun:
   • A salt or ester derived from silicic acid: A silicate is a chemical compound containing silicon, oxygen, and one or more metals, forming a fundamental structural unit of many rocks and minerals.

Usage

• Silicates are the most abundant minerals in the Earth's crust.
• In chemistry, a silicate is classified by its specific anionic structure (e.g., orthosilicate, pyrosilicate).
• The term is used in geology, materials science, and industrial chemistry.

Examples

• Noun:
  • Quartz is a common silicate mineral composed of silicon dioxide.
  • The new material is a synthetic silicate with improved durability.
  • Feldspar and mica are both types of silicate minerals.

Advanced Usage

• "Silicate weathering": A key geological process involving the chemical breakdown of silicate rocks, which consumes atmospheric carbon dioxide.
  • Silicate weathering plays a crucial role in the long-term carbon cycle.

Variants and Related Words

• Silicic (adj): Relating to, containing, or derived from silica or silicon.
  • Silicic acid is the parent compound of silicate salts.
• Silica (n): Silicon dioxide (SiO₂), a hard, unreactive, colorless compound which occurs as quartz and in sandstone and many other rocks.
  • Silica is the primary component of most silicate minerals.

Synonyms

• Silicon-oxygen compound: A more general descriptive term.
• Mineral salt (in specific geological contexts): When referring to the ionic crystalline form.

Notes

• The term "silicate" strictly refers to the chemical compound. Related industrial or common names (e.g., "sodium silicate" or "water glass") are specific variants and not the definition of the base word itself.
