Product Description

Sodium feldspar, a common feldspar mineral, is sodium aluminosilicate (NaAlSi3O8). Most common in pegmatites and felsic igneous rocks such as granite, also in low-grade metamorphic rocks, and in some sedimentary rocks as authigenic soda feldspar. soda feldspar usually forms brittle glassy crystals of various colors. It can be used to make glass and ceramics, but its main significance is that it is a rock-forming mineral.

Sodium feldspar is a sodium terminal mineral of plagioclase solid solution series and alkaline feldspar series. It has a tripod-like structure, and silicon and aluminum are tetrahedrally coordinated to form larger vacancies (ie, lattice positions), which are mainly occupied by cationic sodium. Although all silicon and aluminum atoms occupy tetrahedral positions in this structure, the specifics of their positions vary. The distribution of silicon and aluminum atoms is highly ordered at low temperature, but at a high temperature of about 1100°C, the distribution of atoms is much more disordered.

Typical Chemical Properties

Application of Sodium Feldspar

Sodium feldspar is mainly used in the manufacture of ceramic body ingredients and glazes; soda feldspar is one of the main components of glass mixtures, feldspar contains high alumina and low iron content, which can reduce the amount of alkali; soda feldspar It can also be used as a raw material for enamel, mainly using feldspar and other mineral raw materials to blend into enamel. In addition, soda feldspar is also used in soap, tiles, floor tiles, abrasives and other industries.

1. Glass solvent

Sodium feldspar is one of the main components of 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 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. soda feldspar can also be used to adjust the viscosity of the glass.

2. Ceramics

The albite 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 green body. The use of soda feldspar rock in ceramic production can save electricity, coal and raw materials, 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%; soda feldspar can be used to produce polished bricks, exterior wall tiles, floor tiles, etc.

3. Ceramic fiber

Ceramic fibers are industrially used as filter materials for severely corrosive gases or liquids, and can also be used as thermal insulation, electrical insulation and sound insulation materials. When manufacturing ceramic fibers, adding soda feldspar feldspar can reduce production energy consumption by 2.5%.

4. Enamel glaze

As enamel glaze, soda feldspar is mainly used to blend other mineral raw materials into enamel. The dosage of feldspar is generally 20%~30%. The quality requirement for feldspar is similar to glass grade, but it should be ground finer, Na2O>4%.

5. Chemical raw materials and fillers

As a filler, soda feldspar is widely used in coatings, papermaking, rubber, refractory materials, plastics and other industries. Filler grade soda feldspar (such as used in foam rubber products) is similar to "ceramic grade" in fineness and chemical composition, but a higher free quartz content is allowed. In chemical engineering, soda feldspar powder is added to polyolefin film-forming components to increase film-forming uniformity and transparency.

6. Sodium feldspar jade (water foam jade)

Sodium feldspar jade, commonly known as "Shuimozi (Shuimo jade)" in business and trade. It is a type of jade that is associated (symbiotic) with jadeite. Sodium feldspar is called "water foam" because white "cotton" or "white brain" is often distributed on its white or gray transparent base, which looks like foam in water. Most of the water foam jade is fully transparent and translucent, and less transparent. Common textures are glass, ice, and waxy.

7. Other applications

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