The Secret Ingredient for Sparkling Ceramics and Brilliant Glass
Sodium Feldspar (Na-Feldspar)
Sodium Feldspar, or Na-Feldspar, is a group of aluminosilicate minerals containing sodium. It is widely used in various industries in UK due to its high alumina and alkali content, making it a key component in the manufacture of glass and ceramics.
Specifications
Chemical Composition: NaAlSi3O8
Appearance: Typically white, gray, or shades of red and blue
Mohs Hardness: 6-6.5
Specific Gravity: 2.61-2.64
Crystal System: Triclinic or monoclinic
Refractive Index: 1.533-1.539
Melting Point: 1100-1150°C
Applications:
Glass Manufacturing: Acts as a flux, lowering the melting point of the mixture and enhancing the strength and clarity of the glass.
Ceramics: Provides a necessary component for the vitreous phase, enhancing the mechanical strength and vitrification.
Fillers: Used in the production of paints, plastics, and rubbers to improve product quality and durability.
Enamels and Glazes: Enhances the gloss and smoothness of surfaces.
Benefits
- Improves hardness and durability of final products.
- Enhances the aesthetic appeal with its ability to produce a glassy finish.
- Lowers production costs by reducing the melting temperature of mixtures.
