Specification of Soda Feldspar

Al2O3 19-22% Al2O3 is generally 15-18%, ours is 19-22%, high aluminum can burn quickly at low temperatures
SiO2 65%min
Fe2O3 0.1%±0.05 Fe2O3  less than 0.1%, low iron can increase whiteness
Na2O 11%±0.5 Na2O with a content of more than 10% is high sodium, and sodium improves the gloss and light transmittance of the product
CaO 0.6%max
Whiteness 55° Low iron content will lead to high whiteness, which belongs to high-quality soda feldspar
Sodium feldspar powder from Anyang Lishi Industrial has the advantages of fast burning at low temperatures, increasing whiteness and gloss

Application of Soda Feldspar 

• Raw materials for glass 

Albite powder is one of the main components of a glass mixture. Feldspar contains high alumina and low iron content, which can reduce the amount of alkali. In addition, the process of albite melting into the glass is relatively slow, and the crystallization ability is small, which can prevent crystals from being precipitated during the glass formation process and damage the product. Albite can also be used to adjust the viscosity of the glass.

Soda Feldspar is Used in Glass

• Raw materials for ceramics

The albite mineral powder can act as a barren raw material before the ceramic body is fired, reduce the drying shrinkage and deformation of the body, improve the drying performance, and shorten the drying time. It can be used as a flux filling in the body during firing to make the body Dense and reduce voids, but also improve the light transmittance of the green body. The use of albite rock in ceramic production can save electricity, coal, and ceramics raw material, and reduce production costs to a certain extent.

At present, China has not formulated a unified quality standard for feldspar mineral products, and its general quality requirements are Fe2O3<0.3%~1%(the Fe2O3 of soda feldspar powder of Anyang Lishi Industrial is 0.1%±0.05); albite can be used to produce polished bricks, exterior wall tiles, floor tiles, etc.

Soda Feldspar is used in Ceramics

• Raw materials for refractory

Sodium feldspar’s low coefficient of thermal expansion helps to minimize thermal stress during heating and cooling cycles, thus preventing cracks and fractures in the refractory structure. Additionally, its high alumina content contributes to the formation of mullite, a compound known for its excellent refractory properties. Sodium feldspar also acts as a flux, lowering the melting point of the refractory mixture and facilitating densification during firing.

• Raw materials for coating

Sodium feldspar is utilized in the coatings industry primarily as a filler and extender. Its fine particle size and high alumina content contribute to improved opacity, durability, and scratch resistance in coatings. It also acts as a rheology modifier, enhancing paints and coatings’ flow and leveling properties. Additionally, sodium feldspar serves as a cost-effective alternative to other fillers, helping to reduce production costs while maintaining desired performance characteristics in various coating formulations.

• Raw materials for plastic

Its high alumina content improves plastics’ heat resistance and chemical inertness, making them suitable for various applications. Additionally, sodium feldspar contributes to reducing shrinkage and warping during molding processes. Its compatibility with different polymer matrices makes it a versatile additive in plastic formulations, offering improved performance and cost-effectiveness in producing plastic goods.

• Other applications

Sodium feldspar powder is also used in soap, abrasives, abrasive tools, welding rods, and other industries. The albite in the electrode coating can act as an arc stabilizer and a weld pool protectant.
