Green Manufacturing Reshapes the Industry Chain High-End Quartz Materials Enter a Boom Period for New Applications

— *New Applications of Quartz Materials in the Context of Green Manufacturing* provides an in-depth analysis of the quartz industry's technological evolution and new commercial growth drivers under "Dual Carbon" goals.

Industry News

[Industry Update] Driven by the global push for "Dual Carbon" goals and the deepening transition toward green manufacturing, basic industrial materials are facing unprecedented demands for upgrading. The recently released special report, *New Applications of Quartz Materials in the Context of Green Manufacturing* (hereinafter referred to as the "Report"), has garnered widespread attention across the industry chain. The Report highlights that quartz—often termed the "salt of industry"—is moving beyond traditional, extensive application models. Thanks to its high purity, high heat resistance, low thermal expansion, and excellent electrical properties, it is achieving breakthroughs in green, high-tech sectors such as solar photovoltaics (PV), advanced semiconductors, fiber-optic communications, and next-generation energy storage.

Core Highlights: Empowering Four Key High-Tech Application Scenarios

1. The N-type PV Cell Revolution: High-Purity Quartz Crucibles as the "Key to Efficiency"

As the PV industry shifts toward N-type cell technologies—such as TOPCon, HJT, and BC—the monocrystalline silicon pulling process imposes rigorous demands on the purity and heat resistance of quartz crucibles. The Report indicates:

Replacement with high-purity inner-layer quartz sand: Crucible inner layers made from high-purity quartz materials significantly reduce impurity release during crystal pulling, thereby accelerating monocrystalline silicon growth efficiency.

Superior lifespan and energy efficiency: Enhanced refractoriness and crystallization resistance extend the crucible's service life and drastically reduce energy consumption per gigawatt (GW) of PV silicon wafer production, aligning perfectly with green manufacturing principles.

2. Advanced Semiconductor Manufacturing: Critical Support from High-Purity Quartz Components

In high-temperature and highly corrosive semiconductor manufacturing stages—such as diffusion, oxidation, and etching—high-purity quartz materials (purity >99.999% or "5N") serve as the core substrate ensuring chip yields:

Ultra-high purity and low metal contamination: Minimizing particle precipitation creates a reliable processing environment for advanced manufacturing nodes of 7nm and below.

Localization and Greening of Semiconductor Components: The development of green purification processes has reduced pollution emissions associated with traditional acid-wash purification, striking a balance between material performance and environmental benefits.

3. Optical Fiber and Communication Infrastructure: Ultra-low-loss materials paving the way for low-carbon computing networks

Against the backdrop of the computing economy and 5G/6G infrastructure deployment, the demand for high-purity synthetic quartz glass for low-loss optical fibers has surged. The Report highlights that quartz optical fiber preforms produced using low-carbon synthesis technologies not only enhance signal transmission efficiency but also lower the overall operational energy consumption of data centers.

4. Novel Energy Storage and High-Temperature Thermal Management: Pioneers in emerging industrial applications

Beyond electronics and photovoltaics, high-purity quartz materials demonstrate immense potential in novel energy storage systems (such as high-temperature molten salt thermal storage), aerospace thermal protection, and specialized optics, positioning them as a prime alternative to traditional, highly polluting, and energy-intensive industrial materials.

Technological Breakthroughs: Green purification and recycling as core corporate competencies

The Report emphasizes that the "green" nature of quartz materials is reflected not only in carbon-reduction capabilities at the application stage but also in the transformation of manufacturing processes.

Greening of purification processes: Traditional physicochemical purification methods are evolving toward "eco-friendly composite acid washing combined with high-temperature chlorination for impurity removal," significantly reducing waste acid generation and wastewater treatment costs.

Breakthroughs in synthetic quartz technology: Utilizing pollution-free synthesis techniques—such as Vapor Axial Deposition (VAD) and Outside Vapor Deposition (OVD)—to produce ultra-high-purity quartz, thereby reducing over-reliance on scarce natural high-purity quartz ore resources.

Recycling and reuse systems: Establishing recovery and reprocessing chains for spent quartz components from the photovoltaic and semiconductor sectors to achieve a high-value, closed-loop cycle for quartz resources.

Expert Insights and Business Outlook

"Green manufacturing is not merely a regulatory constraint regarding environmental protection; it is a core engine driving industrial base materials toward the upper end of the value chain. The deep integration of quartz materials into the photovoltaic and semiconductor sectors—two 'super-growth' industries—is redefining their commercial value."

Over the next three to five years, quartz material enterprises possessing high-purity refining technologies, low-carbon green production processes, and upstream resource integration capabilities will secure a dominant position in the new wave of industrial upgrading.

For B2B manufacturers, actively embracing green quartz materials and their high-end applications is not only an essential step in aligning with "Dual Carbon" policies but also a critical breakthrough for enhancing end-product competitiveness and reducing energy consumption across the entire product lifecycle.
