CLIRIK offers a comprehensive range of potassium feldspar crushing and grinding systems. Our technology is designed to optimize your production efficiency, significantly reduce specific energy consumption, and meet the most stringent manufacturing requirements for various potassium feldspar-based products.
Material Introduction
Potassium feldspar, often referred to as orthoclase or K-feldspar, is a framework silicate mineral with the chemical formula KAlSi3O8. It is characterized by its significant potassium oxide (K2O) content and its ability to act as a powerful flux, lowering the melting temperature of silica during industrial processing.
Physically, potassium feldspar is a hard mineral with a Mohs hardness of 6, which serves as a standard on the Mohs scale. It typically appears in flesh-red, white, or grayish-white colors with a vitreous luster. Chemically, it is highly stable and provides a consistent source of alumina and silica, which enhance the mechanical strength and chemical durability of the final products. In its powdered form, its performance is defined by its iron content (Fe2O3)Fe2O3) and particle size distribution. High-purity potassium feldspar is critical for ensuring the transparency and brilliance of high-end glass and the smooth, defect-free surface of fine porcelain glazes.

Industrial Applications
1
200 – 400 Mesh (D97: 75-38μm): Glass & Ceramic Bodies
Applications :
Primarily used as a source of alumina and flux in Glass Manufacturing (containers, flat glass) and as a skeleton material for ceramic bodies.
Advantages :
It improves the chemical durability of glass and controls its viscosity during forming. In ceramics, it acts as a binder that fuses the body components during firing, ensuring structural integrity.
2
800 – 1250 Mesh (D97: 18-10μm): Ceramic Glazes & Frits
Applications :
Essential component for Fine Porcelain Glazes, sanitary ware enamels, and glass frits.
Advantages :
At this fineness, it ensures a rapid and uniform melt, producing a smooth, high-gloss surface. It effectively lowers the firing temperature while enhancing the brilliance and acid resistance of the glaze.
3
1500 – 2500 Mesh (D97: 10-5μm): Specialized Fillers & Welding Rods
Applications :
Used as a functional filler in Latex Paints, specialized rubber compounds, and as a coating ingredient for high-quality welding electrodes.
Advantages :
The increased surface area improves the abrasion resistance and chemical stability of coatings. In welding, it helps stabilize the arc and provides a protective slag for the weld bead.
4
3000 Mesh + (D97: ≤5μm): Precision Electronic Glass & High-End Plastics
Applications :
Specialized functional material for Ultra-Thin Electronic Glass, precision optical components, and as a low-expansion filler for high-end engineering plastics.
Advantages :
The ultra-fine particle size ensures perfect dispersion and high light transmission. It is critical for the production of advanced smartphone screens and electronic substrates where particle consistency and extreme purity are paramount.
