fluor-spar

A geologist examines a piece of fluor-spar in the field.

Definition

1. Noun:
   • A mineral: "fluor-spar" is a mineral consisting of calcium fluoride (CaF₂), typically occurring in cubic crystals and found in various colors such as purple, green, or yellow. It is also known as fluorspar or fluorite.

Usage Examples

• Noun:
  • The mine produces high-quality fluor-spar used in the steel industry. (A mineral used as a flux in metallurgy.)
  • Collectors prize the vibrant purple fluor-spar crystals from this region. (Mineral specimens valued for their color and crystalline form.)

Advanced Usage

• "Fluor-spar flux": a substance added to molten metal to remove impurities.

  • The addition of fluor-spar to the furnace helps lower the melting point of slag. (The mineral acts as a flux in industrial processes.)

• "Optical fluor-spar": a pure, transparent form of fluor-spar used in lenses and prisms.

  • Telescopes often use optical fluor-spar to reduce chromatic aberration. (A high-purity variant employed in precision optics.)

Variants and Related Words
