Uses of Sodium Feldspar

Soda Feldspar has multiple uses across various industries.

Glass Industry:

Sodium Feldspar is used in Glass Industry for:

1. Due to its Alumina content which provides the glass with hardness, durability, and resistance to chemical corrosion.

2. NaO2 and K2O are flex which reduces the melting temperatures of the quartz enabling control of the glass’s viscosity, less energy is used and describes the amount of soda ash needed.

70% of feldspar industrial use is in Glass Industry.

Paints / Plastic / Rubber:

Albite also are used as fillers and extenders in applications such as paints, plastics, and rubber.

Beneficial properties of feldspars include good dispersibility, high chemical inertness, stable pH, high resistance to abrasion, low viscosity at high filler loading, attractive refractive index, and resistance to frosting.


Sodium Feldspar is the second most important ingredient after clay and is used as it provides

1. Act as a fluxing agent to reduce the melting temperature

2. Allow modulation

3. improve the strength, toughness, and durability of the ceramic body.

Enamel frits and glazes:

Soda Feldspar assists the enamel composition, assuring the absence of defects and the neatness of the end product: e.g. enamel frits, ceramic glazes, ceramic tile glazes, sanitaryware, tableware, electrical porcelain, and giftware.


Bonding Agent


Soda Feldspar is used in coatings of welding electrodes for their fluxing properties, particularly for coating electrodes used in the manual arc process, which is popular for welding ferrous alloys in structural steelwork, shipbuilding, general fabrication industries, and hard-facing. Albite’s fluxing properties act as an arc stabilizer and weld pol protector.
