Applications

  • Ceramics: Acts as a flux, lowering firing temperature and enhancing strength.
  • Glass: Improves viscosity control and reduces melting point of quartz.
  • Fillers: Used in paints, plastics, and rubber for improved durability and performance.

Key Properties

  • Composition: Aluminosilicate mineral with sodium as the dominant element.
  • Abundance: The most widespread mineral group in the Earth’s crust.
  • Rock Formation: Present in igneous (e.g., granite), metamorphic, and some sedimentary rocks.
  • Hardness: 6–6.5 on Mohs scale, capable of scratching glass.
  • Cleavage: Distinct cleavage planes at near 90°, giving a blocky structure.

Other Uses

Fillers: Used in paints, plastics, and rubber for improved durability and performance.
