High-durability quartz solutions optimized for Southeast Asian industrial conditions
Lianyungang Southeast Quartz Products Co., Ltd. is a professional manufacturer with over 10 years of experience in the quartz industry. Located in Donghai County, Jiangsu, China, the leading quartz product distribution center on the Eurasian continent, we specialize in producing a comprehensive range of customized quartz products tailored precisely to our clients' specifications.
As Indonesia undergoes a monumental industrial shift—driven by downstream mineral processing, solar energy adoption, and high-tech manufacturing—our mission is to supply premium-grade, high-purity quartz furnace tubes and components directly to Indonesian companies. By combining the natural raw material wealth of Donghai with state-of-the-art thermal processing technology, we guarantee quartz products that withstand the most extreme thermal and chemical environments in modern factories.
Why high-purity quartz tubes are critical for the archipelago's economic expansion
Indonesia is rapidly pivoting toward green energy. With initiatives like the Cirata Floating Solar Project and localized solar module assembly plants in industrial zones like Cikarang and Karawang, the demand for solar-grade silicon wafers has skyrocketed.
Our high-purity quartz tubes act as the primary reaction chambers during the diffusion and oxidation stages of solar cell fabrication. The ultra-low impurity profile (SiO2 ≥ 99.99%) prevents contamination of silicon wafers, ensuring maximum photoelectric conversion efficiency for Indonesian solar panels.
With the world's largest nickel reserves, Indonesia has become the global hub for EV battery precursor production. Smelting operations in Morowali (IMIP) and Weda Bay require precise high-temperature laboratory testing and pilot-scale chemical processing.
Our custom-sized quartz furnace tubes and silica reactors provide unparalleled thermal shock resistance. Capable of continuous operation at 1100°C and short-term exposure up to 1450°C, they are the ideal containment solutions for analyzing and processing aggressive nickel compounds and lithium-battery precursors.
As the Indonesian government promotes the "Making Indonesia 4.0" roadmap, electronics clusters in Batam and West Java are scaling up production. Semiconductor wafer fabrication requires cleanroom-compatible materials that do not outgas under extreme heat.
We supply high-temperature quartz boats and rings designed to hold wafers securely during chemical vapor deposition (CVD) and physical vapor deposition (PVD) processes, providing structural stability and preventing contamination.
From the petrochemical hubs of Cilegon to the research laboratories of Universitas Indonesia (UI) and ITB, scientific experimentation relies on chemically inert apparatuses. Fused silica offers superior resistance to almost all acids (except hydrofluoric), making it indispensable for high-temperature chemical reactions.
Innovating quartz technology to meet modern Indonesian manufacturing standards
Our quartz tubes feature a silica content exceeding 99.99%, minimizing metallic impurities (Fe, Al, Ca, Mg) to protect sensitive semiconductor and chemical processes from contamination.
Extremely low coefficient of thermal expansion (5.4×10⁻⁷/°C) allows our tubes to withstand rapid heating and cooling cycles without cracking or structural deformation.
From micro-diameter laboratory tubes to massive, oversized industrial furnace tubes, we customize diameters, wall thicknesses, and lengths to fit any furnace design.
Quartz products have a wide range of applications, covering industries such as semiconductors, photovoltaics, optics, chemicals, and scientific research. Below are some examples of relevant scenarios:
How Lianyungang Southeast Quartz ensures safe and fast delivery to Indonesia
We understand that quartz products are fragile and require meticulous handling. Our factory utilizes export-grade wooden crating, custom-fit foam packaging, and vacuum sealing to prevent moisture and physical impact during transit.
We offer direct shipping routes from Shanghai/Lianyungang ports to major Indonesian ports including Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), and Belawan (Medan), ensuring smooth customs clearance and competitive transit times.
No two industrial furnaces are identical. Our engineering team works closely with Indonesian plant managers and laboratory technicians to design quartz tubes according to custom drawings. Whether you require flanged ends, ground joints, or slotted tubes, we provide precise CAD drawing confirmation before starting production.
