Explore our flagship quartz plate products engineered for demanding chemical processing environments — precision-cut, high-purity, and fully customizable.
Quartz plates deliver unmatched performance properties that make them indispensable across modern chemical processing systems.
Fused silica quartz plates withstand continuous operating temperatures up to 1200°C and can endure rapid thermal cycling without cracking — a fundamental requirement in chemical reactors, acid-handling systems, and high-temperature processing lines.
Sustained performance up to 1200°C with excellent thermal shock resistance across extreme temperature gradients.
Resistant to virtually all acids, alkalis, and aggressive solvents including HF, H₂SO₄, and HNO₃ environments.
Minimal metallic contamination ensures process integrity in ultra-clean chemical and semiconductor workflows.
CNC-machined to exact tolerances — any shape, thickness, or perforation pattern to match your equipment design.
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.
The global demand for high-performance quartz components in chemical engineering is accelerating, driven by new-energy, semiconductor, and advanced materials industries.
The global fused quartz market is projected to exceed USD 3.8 billion by 2030, with chemical engineering applications representing one of the fastest-growing segments. Increased demand for acid-resistant, high-purity components in petrochemical, pharmaceutical, and specialty chemical plants is a primary growth driver. Manufacturers who can supply precision-machined quartz plates at scale are positioned for significant commercial opportunity.
Modern chemical plants increasingly require non-standard quartz components tailored to proprietary reactor geometries and process parameters. The trend is moving away from off-the-shelf parts toward fully engineered quartz assemblies. This shift rewards suppliers with strong R&D capabilities and flexible CNC fabrication infrastructure — exactly the model adopted by leading Chinese quartz manufacturers serving global OEM clients.
Green chemistry initiatives and tightening environmental regulations are pushing chemical engineers to adopt materials that minimize contamination and enable cleaner processes. Fused silica quartz plates, with their near-zero ionic leaching and inert surface chemistry, are replacing borosilicate glass and metallic components in reactors, distillation columns, and heat exchangers — aligning perfectly with sustainability goals.
The rapid expansion of lithium battery production, hydrogen fuel cells, and photovoltaic manufacturing has created new demand for quartz plates used in electrode processing, electrolyte handling, and thin-film deposition chambers. Chemical engineering systems within these new-energy factories require materials that can handle corrosive electrolytes and high-temperature cycling — quartz is the material of choice.
Stringent GMP standards in pharmaceutical manufacturing demand ultra-clean, non-reactive surfaces for synthesis reactors, distillation equipment, and analytical instruments. Quartz plates and vessels are increasingly specified in API (Active Pharmaceutical Ingredient) production lines, where metallic contamination at even parts-per-billion levels can invalidate entire batches. This represents a high-value, high-growth niche for premium quartz suppliers.
China's Donghai County — home to Lianyungang Southeast Quartz Products — holds some of the world's highest-grade natural quartz ore deposits. Combined with advanced processing infrastructure and competitive manufacturing costs, Chinese quartz producers now supply over 60% of global industrial quartz components. Export volumes to Europe, North America, and Southeast Asia have grown steadily year-on-year, establishing China as the undisputed center of the global quartz supply chain.
From acid digestion systems to high-temperature reactors, quartz plates serve as the structural and functional backbone of critical chemical engineering equipment.
Quartz plates are not merely passive structural components — in advanced chemical engineering systems, they function as reaction substrates, optical windows, thermal barriers, and corrosion-resistant liners, each application demanding specific purity grades and dimensional tolerances.
In analytical chemistry and industrial purification, quartz plates form the base and wall components of tri-acid (HF/HNO₃/HClO₄) digestion vessels. Their resistance to hydrofluoric acid — which attacks virtually every other material — makes them irreplaceable. Quartz plates used here must achieve SiO₂ purity ≥99.99% and surface roughness Ra ≤0.4μm to prevent acid trapping and ensure complete vessel cleanability between batches.
Chemical vapor deposition (CVD) reactors, pyrolysis chambers, and calcination furnaces use quartz plates as observation windows and thermal liner panels. Operating at 800–1200°C, these plates must maintain dimensional stability and optical clarity. Custom-drilled quartz plates with thermocouple ports and gas inlet fittings are increasingly requested by reactor manufacturers integrating real-time process monitoring.
Quartz distillation plates and column packings are used in the production of ultra-pure solvents, acids, and specialty chemicals where metallic contamination from stainless steel equipment is unacceptable. Quartz's thermal conductivity profile and chemical inertness make it ideal for both atmospheric and vacuum distillation columns handling aggressive organic and inorganic compounds.
In nuclear fuel reprocessing and radioactive waste handling facilities, quartz plates serve as radiation-transparent viewing windows and containment vessel components. Their resistance to radiation-induced browning (compared to standard glass) and their ability to be decontaminated with strong oxidizing acids make them the preferred material for hot-cell windows and glove-box panels in nuclear chemical engineering applications.
Chlor-alkali plants, water electrolysis systems for green hydrogen production, and electrochemical synthesis reactors use quartz plates as electrode separators and cell dividers. Quartz's electrical insulation properties (resistivity >10¹⁸ Ω·cm) combined with its chemical resistance to chlorine, caustic soda, and sulfuric acid electrolytes make it a technically superior alternative to PTFE and ceramic dividers in high-current-density applications.
Photochemical synthesis — a growing field in pharmaceutical and fine chemical manufacturing — requires reactor windows that transmit deep UV radiation (185–400nm). Fused silica quartz plates offer >90% UV transmittance in this range, enabling efficient photocatalytic reactions. Custom-fabricated quartz windows with anti-reflection coatings are now standard components in industrial photoreactors used for ozone generation, water treatment, and UV-initiated polymerization processes.
