Engineered to withstand up to 1200°C continuous operation, offering exceptional chemical inertness and thermal shock resistance for modern Nigerian refineries, metallurgical assays, and clean-tech plants.
How Nigeria's diversifying economic hubs—from the Lekki Free Trade Zone to Port Harcourt and Kaduna—are driving the demand for advanced thermal quartz components.
As Nigeria accelerates solar off-grid mini-grids and utility-scale renewable projects, domestic module assembly and cell testing plants require high-purity quartz wafer carriers, diffusion boats, and furnace liners to ensure flawless silicon wafer throughput under severe thermal cycling.
With massive refining infrastructures like the Dangote Petroleum Refinery and operations across the Niger Delta, specialized high-temperature quartz boats and digestion vessels are essential for elemental sulfur analysis, catalyst calcination, and ultra-trace petroleum chromatography.
Nigeria’s vast deposits of lithium, tantalite, gold, and tin ores in Nasarawa, Plateau, and Kogi states necessitate robust laboratory quartz boats, crucibles, and combustion tubes capable of surviving aggressive fluxing agents and temperatures up to 1200°C during mineral quality testing.
Donghai County Leef Quartz Technology Co., Ltd. was founded in 2022 as a subsidiary of Lianyungang Southeast Quartz Products Co., Ltd., which was established in 2015. We are located in Donghai County, Lianyungang City, Jiangsu Province — known as "China Crystal Capital" and a national-level silicon material industry base.
Blessed with superior high-purity quartz ore resources, Donghai is a core production area of quartz raw materials in China. Relying on local high-grade quartz veins, we focus on the deep processing of quartz glass, and are a professional manufacturer integrating design, production, sales and foreign trade.
With mature production technology, strict quality control and complete customized services, we have become a trusted supplier of quartz consumables for industries including photovoltaics, semiconductors, laboratories, chemical engineering and lighting across Nigeria, ECOWAS member states, and the international marketplace.
We operate standardized production workshops equipped with a full set of advanced equipment for quartz cutting, grinding and high-temperature forming, establishing a complete production line from quartz processing to finished product inspection.
Backed by a professional production management team with over 10 years of industry experience, we specialize in process optimization and customized manufacturing. We support rapid prototyping and mass production for various complex products, with an annual capacity of hundreds of thousands of pieces.
We accept both small-batch custom orders and large-scale bulk orders with efficient delivery. By continuously upgrading production techniques, we improve product precision and stability, providing cost-effective quartz solutions for global customers—with dedicated freight routing to Nigeria via Lagos Port (Apapa / Tin Can Island) and Murtala Muhammed International Airport cargo hubs.
All products are made of high-purity fused quartz raw materials, featuring excellent heat resistance (up to 1200°C), thermal shock resistance, corrosion resistance, high light transmittance and electrical insulation. They are widely used in photovoltaic manufacturing, semiconductor production, chemical laboratory analysis, chemical anti-corrosion treatment, lighting equipment and other general industrial and experimental applications. We also provide custom processing for special-shaped products according to customer drawings to meet personalized requirements.
High-purity fused quartz tubes, quartz furnace tubes, quartz bell jars, quartz boats, quartz lamp holders, quartz crucibles, and customized tube reactors designed for high-heat industrial furnaces in Nigeria.
Quartz baskets, quartz tanks, quartz cups, exhaust tubes, condensation bottles, boat racks, various quartz boats, quartz rods, quartz plates, quartz rings and other customized parts built to client blueprints.
Quartz beakers, condensers, distillers, lamp caps, spectrophotometer cuvettes, and acid washing tanks utilized across Nigerian university research laboratories and industrial testing institutes.
Solving extreme heat, chemical wear, and logistical challenges with end-to-end quality assurance and robust export packaging.
Our quartz boats and crucibles exhibit virtually zero reactivity when exposed to corrosive acids (excluding hydrofluoric acid) and strong chemical vapours, eliminating sample contamination during geochemical assays in Nigerian gold, lithium, and base metal processing facilities.
To withstand long-distance maritime shipping to Apapa/Onne ports or expedited air cargo to Abuja/Lagos, each quartz boat is individually encapsulated in multi-layer shock-absorbing EVA foam, vacuum-sealed, and packed in reinforced plywood crates to prevent transit micro-fractures.
Whether your Nigerian operation runs tubular horizontal furnaces, CVD systems, or vertical batch processing, we cut, slot, and fire-polish wafer carrier slots with sub-millimeter precision according to your exact dimensional drawings and thermal expansion parameters.
