China's feldspar industry has transitioned from primary resource processing to refined purification and functional customization, driven by growing demand for fluxing, filling, and performance-specific functions in downstream industries. In the 1980s and 1990s, relying on high-quality feldspar resources in Junggar (Xinjiang), Jingdezhen (Jiangxi), Liling (Hunan), and other regions, the industry focused on mining and simple crushing. Products were mostly ordinary feldspar powder, mainly used for ceramic glazes/bodies, glass raw materials, and common abrasives, characterized by high impurities (iron, titanium), variable composition, and limited added value.

Since the turn of the century, the industry has transformed through flotation for impurity removal, fine classification, and application-specific differentiation. Driven by the need for high-end ceramics (tableware, sanitaryware), lightweight glass, and precision electronic materials, as well as stricter environmental policies. High purity has been achieved through magnetic separation and flotation. Ultra-fine grinding has reached fineness levels of 3000 mesh or more, enabling the development of ceramic-grade, glass-grade, and electronic-grade feldspar products, with breakthroughs in high-end ceramic glazes, photovoltaic glass, and electronic ceramic substrates.

In recent years, high-end demands from new energy (cathode material additives for lithium batteries), semiconductors (fillers for encapsulation), and high-end building materials (aggregates for engineered stone) have surged. Coupled with the evolution of relevant standards, the industry is accelerating its upgrade toward efficient resource utilization and high-end product specialization. Today, China is the world's largest producer and consumer of feldspar. Products include potassium feldspar, sodium feldspar, and calcium feldspar, covering raw ore, conventional feldspar powder, high-purity feldspar powder, and ultra-fine feldspar powder. These are widely used in dozens of fields, including ceramics, glass, electronics, new energy, and building materials.

We have set up a dedicated feldspar mineral testing team. Based on product type and application scenario (ceramic glaze, photovoltaic glass, electronic filler, lithium battery additive), we provide customized testing services—including composition analysis (K₂O/Na₂O content), fineness testing, impurity screening (Fe, Ti, Ca), and chemical stability evaluation—helping products build advantages in performance optimization and regulatory compliance.
