Potassium Feldspar: an Industrial Treasure for Many Applications

Potassium feldspar, chemical formula K₂O·Al₂O₃·6SiO₂, usually also known as orthoclasite, belongs to the monoclinic crystal system mineral, the common color is meat red, white or gray. Potassium feldspar series covers orthoclase, microplagioclase, through-feldspar and other mineral types. As a multifunctional aluminosilicate mineral, potassium feldspar has shown irreplaceable important value in many industrial fields.

I. Core role in the glass industry

Potassium feldspar plays a key role in the glass industry. As the main component of glass mixture, usually accounting for between 50%-60%, its main role is to provide alumina (Al₂O₃), while reducing the glass melting temperature, reduce the amount of alkali. This feature not only optimizes the glass production process, but also effectively prevents the crystallization of glass in the molding process to ensure the quality of glass. With its advantages of wide melting range and small crystallization energy, potassium feldspar can accurately adjust the viscosity of glass, making it easier to process and shape.

For high-end glass products, such as TV imaging glass shell, high quality potassium feldspar is an indispensable raw material. It can significantly improve the light transmittance and durability of glass, and meet the strict performance requirements of high-quality glass products.

II. High quality raw materials for ceramic manufacturing

Potassium feldspar also has a wide range of applications in ceramic manufacturing, whether in the billet or glaze, play an important role.

Blank: potassium feldspar can reduce the drying shrinkage rate of ceramic blank, accelerate the formation of mullite, so as to effectively improve the mechanical strength and light transmittance of ceramic products. The amount in billet can reach 30%, which provides a strong guarantee for the quality of ceramic products.

Glaze: in ceramic glaze, the proportion of potassium feldspar is generally between 10% and 35%. It gives ceramic products better finish and color stability, so that the appearance of ceramic more exquisite, lasting bright color.

In addition, the low melting point characteristics of potassium feldspar (about 1150 ° C) bring significant process advantages to ceramic production, which can effectively reduce the firing temperature, optimize energy consumption, reduce production costs, and improve production efficiency.

III.  Excellent additives for enamel and building materials

Enamel raw materials: in enamel raw materials, the proportion of potassium feldspar can reach 20%-30%. It can significantly enhance the surface finish of enamel products, make the surface of enamel products more smooth and delicate, improve the appearance quality and performance of products.

Building materials: As a concrete additive, potassium feldspar can improve the compressive strength and working performance of concrete. It can enhance the structural stability of concrete and improve its durability, while optimizing the workability of concrete for easy construction operation, providing a high-quality raw material choice for the construction industry.

IV. Abrasive and special industrial multifunctional materials

Abrasives: Potassium feldspar is widely used in the production of light abrasives due to its moderate hardness (Mohs hardness 6), accounting for between 28% and 45%. It can meet the grinding processing needs of different precision and hardness requirements, providing reliable raw material support for the abrasive industry.

Special industrial materials: potassium feldspar can also be used to produce fireproof calcium silicate board and welding electrode and other special industrial materials. In the fireproof calcium silicate board, it gives the material good fire performance and stability; In the production of electrode, potassium feldspar helps to improve the welding performance and quality of electrode, to meet the specific requirements of material properties in special industrial fields.

V. Characteristic applications in agriculture and other fields

Potassium fertilizer preparation: Through purification treatment, potassium feldspar can convert water-soluble potassium resources into potassium fertilizer, providing an important nutrient source for agricultural production. This application helps to improve soil fertility, promote the growth and development of crops, and contribute to the sustainable development of agriculture.

Decoration and gemstone: beautiful potassium feldspar can also be used as a second-class gemstone or decorative stone. Its unique color and texture add artistic charm to the jewelry design and decoration industry, and can be used to make a variety of exquisite ornaments and decorations to meet people's pursuit of beauty.

Although the global reserves of potash feldspar are about 7.9 billion tons, the deposits are relatively small. Domestic potassium feldspar is often associated with iron impurities, for this, we use advanced wet high gradient magnetic separator and other processes for purification, iron removal efficiency up to 70%-90%, to ensure that the quality of potassium feldspar products to meet the needs of various industries. At the same time, relying on color sorter and other technologies to optimize the quality of potassium feldspar, enhance its competitiveness in the market.
