Electronic-grade Silicon Dioxide with a Purity of over 99.99%: In-depth Analysis of the Global and Domestic Markets, Applications, and Prospects

Electronic-grade high-purity silicon dioxide (SiO₂ ≥ 99.99%) is a core material for strategic industries such as semiconductors, photovoltaics, and optical fiber communication. Its purity, impurity control, and physical properties directly affect the performance of downstream products. The following is an in-depth analysis from four aspects: the current situation of the global and domestic markets, core applications, future trends, and challenges.

I. Current Situation of the Global and Domestic Markets

International Standards and Competition Landscape

Technical Standards: In the international high-end market, the benchmark is SiO₂ ≥ 99.995% (4N5) and the impurity content is less than 50μg/g. The requirements for semiconductor grade are even higher (4N8 - 5N).
Monopoly Pattern: Covia (formerly Sibelco in the United States) dominates the global supply. Its IOTA series products account for more than 70% of the semiconductor-grade market share, with extremely high technical barriers, such as ultra-pure purification and particle morphology control.
Domestic Progress: The localization rate of 4N5-grade high-purity quartz sand has reached more than 60% (enterprises like Jiangsu Pacific Quartz Co., Ltd.), but the 4N8 - 5N grade still highly depends on imports (imports account for more than 90%). The spherical silica micro powder of Lianrui New Materials, which is used for chip packaging, has broken the monopoly of Denka in Japan, and its global market share increased to 15% in 2023.

II. Core Application Fields and Demand Drivers

Semiconductors and Electronics (Accounting for 45%)

Wafer Manufacturing: Used as a carrier for photoresist and CMP polishing solution. The demand for 12-inch silicon wafers has surged. The domestic monthly production capacity has reached 800,000 pieces, and it is expected to exceed 2 million pieces in 2025.
Advanced Packaging: Spherical silica micro powder is filled in epoxy molding compound (EMC), reducing the coefficient of thermal expansion (CTE) to below 3ppm/°C to meet the requirements of HBM (High Bandwidth Memory) and AI chips.
High-frequency and High-speed Substrates: Low Dk/Df (Dielectric Constant/Loss Factor) silica micro powder is used for PCBs of 5G base stations and servers. The market size will increase by 12% annually from 2023 to 2030.
Biomedicine: Porous silica gel microspheres used as chromatographic packing materials, with a domestic substitution rate of less than 10%.
Optics and Aerospace: High-purity quartz glass is used for deep ultraviolet laser lenses and satellite lenses, with a light transmittance of > 99.99%.

III. Future Trends and Growth Drivers

Demand Outbreak Points

Advanced Packaging: 3D packaging and Chiplet technology will drive the demand for spherical silica micro powder. The global market is expected to reach 430,000 tons in 2028 (with a compound annual growth rate of 8.5%).
AI and High-speed Computing: The demand for Ultra Low Loss-grade silica micro powder (Df ≤ 0.001) has surged, with a unit price of over 50,000 yuan per ton, which is a 300% premium compared to ordinary products.
Purification Process: The chemical synthesis method (tetrachlorosilicon vapor deposition) will replace the traditional mineral purification method, with a purity that can reach 6N level and a cost reduction of 30%.
Morphology Control: Breakthroughs in nanoscale spheroidization (particle size ≤ 0.5μm) and monodispersity (CV value < 3%) technologies to be suitable for processes below 3nm.
Policy Support: It has been included in the key material catalog of "Made in China 2025". The price of domestic semiconductor-grade products is 20% - 30% lower than that of imported products.
Capacity Expansion: Lianrui New Materials plans to reach a spherical powder production capacity of 60,000 tons per year in 2025, seizing 15% of the global market share.

IV. Key Challenges and Risks

Resource Bottlenecks: The global reserves of high-purity vein quartz ore are less than 10 million tons, and China only accounts for 15%. The energy consumption for purification is as high as 2000kWh/ton.

International Competition: Patent barriers of enterprises in Europe, America, and Japan, such as Covia's patent for "high-temperature chlorination purification", limit the diffusion of technology.

Technical Gap: The content of metal impurities (such as Al and Fe) in domestic 4N8-grade products is still 50% - 100% higher than that of imported products.

Conclusion

Electronic-grade high-purity silicon dioxide is a "bottleneck" material and strategic resource. The global market will maintain a growth rate of more than 10% in the next five years. Domestic enterprises need to focus on optimizing the purification process (such as reducing costs through biological leaching methods), achieving breakthroughs in high-end applications (domestication of semiconductor grade), and accelerating the integration of the industrial chain (such as the integration of quartz ore, purification, and deep processing) to occupy a core position in the waves of AI and new energy.
