High-Purity & Heat-Resistant Quartz Solutions for High-Temperature Industrial Applications
Company Profile
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.
Global Quartz Excellence
Southeast Quartz is dedicated to delivering superior performance in extreme environments. Our solutions are engineered for durability, precision, and efficiency.
01. Customer Supreme
Adhering to the philosophy of "Quality First, Customer Supreme, Innovation-Driven, Integrity Management", the company has established a complete quality inspection system tailored to global industrial demands.
02. Quality Control
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 zero-leakage operations.
03. Customized Services
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.
Heat-Resistant Quartz Lamp Holders & Solutions
In high-intensity industrial heating, ultraviolet (UV) curing, and semiconductor processing, standard components fail. Our Heat-Resistant Quartz Lamp Holders are engineered to withstand continuous operating temperatures up to 1200°C while maintaining exceptional mechanical stability and electrical insulation.
Thermal Shock Resistance
Fused quartz possesses a near-zero coefficient of thermal expansion. Our lamp holders can transition rapidly between extreme temperatures without cracking or structural degradation, ensuring long-term operational safety.
Superior Electrical Insulation
At high temperatures, electrical leakage can ruin sensitive equipment. Fused silica offers outstanding dielectric strength, preventing electrical arc-overs even in high-voltage UV curing systems and halogen lamp setups.
Chemical & Corrosion Inertness
Resistant to acids, halogens, and organic solvents, our quartz holders are ideal for semiconductor chambers, chemical processing units, and laboratories where corrosive gases are frequently present.
We offer customized configurations including single-ended, double-ended, slotted, and multi-pin quartz lamp holders. Whether you are running a high-power UV sterilization system or an epitaxial semiconductor reactor, our engineering team can design the perfect solution for your thermal environment.
