Silicate is the most abundant group of rock-forming minerals in the Earth's crust (comprising over 75% of rocks). Its rock composition (mineral assemblage, elemental content, crystal structure) directly determines its physical and chemical properties as well as its suitability for specific applications. The industry's development has always been fundamentally supported by precise compositional analysis. In the 1980s and 1990s, silicate compositional analysis was limited to crude measurement of major and minor elements. Relying on natural mineral resources such as feldspar, quartz, and mica, only major components like SiO₂ and Al₂O₃ were determined using chemical titration methods. Due to the lack of detailed analysis of impurities (e.g., clay minerals, iron and titanium oxides) and variations in crystal structure, issues such as insufficient strength in building materials and fluctuating insulation properties in electronic materials frequently occurred. Analysis primarily served basic fields like ordinary cement and construction aggregates.

Since the turn of the century, the demand for material performance stability in high-end manufacturing has driven the transformation of compositional analysis toward comprehensive quantification and structural characterization. Techniques such as X-ray diffraction (XRD), X-ray fluorescence (XRF), and scanning electron microscopy (SEM) have been employed. This enables determination of the quartz/feldspar/clay mineral ratio, trace-level detection of minor elements (e.g., Fe₂O₃, TiO₂, K₂O), and characterization of crystal development. Consequently, specialized products have been developed, including low-iron high-silica type, high-alumina temperature-resistant type, and low-impurity electronic-grade materials, enabling breakthroughs in applications like photovoltaic glass, electronic ceramics, and refractories.

In recent years, stringent purity requirements in new energy (e.g., impurities ≤ 10 ppm in silicates for lithium batteries) and precise control over adsorbent silicates in environmental remediation, coupled with evolving standards, have extended compositional analysis to the full spectrum of mineral phase identification, hazardous element screening, and structure-property correlation. Currently, China's silicate rock compositional analysis technology covers the entire value chain—from raw material exploration and production process control to high-end application support. It can precisely characterize compositional differences from common granite to high-purity quartz sand, providing a core basis for material selection and quality control across fields like building materials, electronics, new energy, and environmental protection.

Our dedicated silicate rock compositional analysis team provides customized services for exploration, production, and application scenarios. These include qualitative/quantitative mineral composition analysis, major/minor/trace element detection, crystal structure characterization, hazardous impurity screening, and composition-property correlation analysis, enabling precise matching between composition and application requirements.
