High-purity fused silica quartz solutions engineered for demanding industrial environments across France and the EU.
Lianyungang Southeast Quartz Products Co., Ltd., established in 2015, is located in Donghai County, Lianyungang City, Jiangsu Province — a national base for silicon material industry. As a professional manufacturer integrating R&D, design, production, sales and import & export trade, the company relies on the superior high-quality quartz ore resources in Donghai County, deeply engages in the deep processing of quartz glass, and has become a core supplier of quartz consumables for photovoltaic, semiconductor, laboratory, chemical, lighting and other industries with mature production technology, strict quality control system and complete customized services.
The company has standardized production workshops, advanced quartz processing equipment and a professional R&D team, with full-process production capacity from quartz raw material processing to finished product manufacturing. It can produce a full range of quartz products, including high-purity fused quartz tubes, quartz furnace tubes, quartz bell jars, quartz boats, quartz lamp holders, quartz crucibles, quartz instruments (beakers, condensers, distillers, etc.), and tri-acid purification equipment. All products are made of high-purity fused quartz raw materials, featuring excellent high-temperature resistance (up to 1200℃), thermal shock resistance, corrosion resistance, high light transmittance and good electrical insulation performance, which can meet the demanding working conditions such as vacuum environment, high-temperature sintering, atmosphere control and precision experiments.
France's advanced industrial landscape creates strong demand for precision quartz components across multiple high-tech sectors.
France is one of Europe's most industrially advanced nations, home to world-class semiconductor fabrication facilities, leading photovoltaic research centers, and a robust chemical engineering sector. The country's strong push toward energy independence and technological sovereignty has created unprecedented demand for large-diameter quartz tubes used in thermal processing, diffusion furnaces, and CVD systems. French manufacturers increasingly source precision quartz components from certified global suppliers who can meet EU quality standards and RoHS compliance requirements.
France has committed to producing 40% of its electricity from renewable sources by 2030, driving massive investment in solar panel manufacturing and research. Large-diameter quartz tubes are essential components in the production of high-efficiency solar cells, used in diffusion furnaces and oxidation processes. French photovoltaic research institutes such as CEA-INES in Chambéry rely on ultra-pure quartz tube systems to develop next-generation silicon heterojunction and perovskite solar technologies that will shape Europe's clean energy future.
France hosts several major semiconductor and microelectronics hubs, including the Grenoble technology cluster — often called "Silicon Valley of the Alps" — where companies like STMicroelectronics operate advanced chip fabrication plants. These facilities require large-diameter quartz furnace tubes for high-temperature annealing, oxidation, and LPCVD processes. The recent EU Chips Act, which aims to double Europe's semiconductor market share by 2030, is expected to further accelerate French fab expansions, creating sustained long-term demand for high-specification quartz components.
France is home to globally recognized research institutions including CNRS (Centre National de la Recherche Scientifique) and numerous pharmaceutical companies such as Sanofi. These organizations require high-purity quartz glassware and large-diameter tubes for corrosive chemical handling, UV spectroscopy, and high-temperature synthesis processes. The superior chemical inertness and thermal stability of fused silica quartz makes it the material of choice for French laboratories conducting cutting-edge research in materials science, nanotechnology, and pharmaceutical development.
Key technology and policy trends shaping the future of large-diameter quartz tube applications across French and European industries.
The European Chips Act commits €43 billion to double EU semiconductor production by 2030. French fabs are expanding capacity, creating sustained demand for large-diameter quartz furnace tubes and process equipment components at scale.
France's REPowerEU commitments and domestic solar manufacturing incentives are driving the construction of new photovoltaic production lines, each requiring high-purity quartz tubes for wafer diffusion and oxidation processes.
France's National Hydrogen Strategy allocates €7 billion to green hydrogen development. High-purity quartz components are critical in electrolysis equipment and hydrogen purification systems being developed by French energy companies.
French manufacturers are adopting Industry 4.0 technologies, requiring precision quartz components with tighter tolerances and custom geometries. Demand for large-diameter tubes with diameters exceeding 200mm is growing rapidly in advanced process equipment.
EU environmental regulations and French industrial sustainability commitments are raising purity requirements for process materials. Ultra-high-purity quartz tubes (99.99%+ SiO₂) are increasingly specified to reduce contamination and improve process yields.
France's aerospace industry, led by Airbus and Thales, along with CNES space agency programs, demands high-performance fused silica optical components. Large-diameter quartz tubes serve as critical elements in satellite optics, laser systems, and infrared sensing applications.
Our large-diameter quartz tubes serve critical roles across France's most technologically advanced industries.
Technical advantages that make our quartz tubes the preferred choice for French and European industrial buyers.
Withstands continuous operating temperatures up to 1200℃ and instantaneous temperatures up to 1450℃, making them ideal for high-temperature sintering and thermal diffusion processes in French semiconductor fabs.
Manufactured from premium Donghai County quartz ore with ultra-high purity, ensuring minimal contamination in critical semiconductor and photovoltaic processes where even trace impurities can compromise yields.
Resistant to virtually all chemicals except hydrofluoric acid, making our tubes ideal for corrosive chemical processing environments in French pharmaceutical and chemical research facilities.
Superior optical transmission across UV, visible, and infrared spectra enables use in photolithography, UV curing, and infrared heating applications critical to French electronics and materials research.
Extremely low coefficient of thermal expansion (0.54×10⁻⁶/℃) provides outstanding thermal shock resistance, ensuring structural integrity during rapid temperature cycling in industrial processes.
Complete customization of diameter (up to 600mm+), wall thickness, length, and end configurations to match exact equipment specifications of French and European OEM manufacturers and research institutions.
Adhering to the philosophy of "Quality First, Customer Supreme, Innovation-Driven, Integrity Management", the company has established a complete quality inspection system. All products undergo multiple tests such as helium mass spectrometry leak detection, pressure resistance test and purity test before leaving the factory to ensure stable performance, no impurities and no leakage. Meanwhile, the company provides flexible customized services, and can customize product sizes, structures and specifications according to customers' equipment parameters and process requirements, quickly responding to personalized orders.
