Import Arc Fused Quartz Crucibles With Large Size — Buy in wholesale FOB from Supplier in China

Arc Fused Quartz Crucibles with Large Size from Nantong Robuster Quartz Co., Ltd. are engineered for high-temperature semiconductor and photovoltaic applications, featuring a silica purity exceeding 99.9% SiO2. The square-format crucibles are available in sizes ranging from 220 mm to 1100 mm, with specific dimensions including 1100 mm (1050x1050x550 mm), 900 mm (878x878x480 mm), and 720 mm (720x720x420 mm), while circular variants span 100 mm to 610 mm in diameter. These crucibles deliver exceptional thermal stability and heat preservation, critical for single crystal growth processes in wafer pulling and PV ingot casting.

The material composition ensures low thermal expansion (0.9x10^-6 °C^-1 from room temperature to 1000 °C) and a maximum operating temperature of 1600 °C, with a volume density of 1.67 g/cm³ and apparent porosity of 12.5%. Typical industry standards for fused quartz crucibles include high resistance to thermal shock, low impurity levels, and consistent dimensional tolerances to prevent contamination in sensitive manufacturing environments. These crucibles are designed to withstand repeated thermal cycling without degradation in performance.

Primary buyers include semiconductor manufacturers, solar PV producers, and metallurgical processors requiring large-format crucibles for sintering and crystal growth. The crucibles are critical consumables in supply chains where precision, purity, and thermal stability directly impact yield and product quality. Buyers should confirm compatibility with their specific process parameters, including temperature profiles and mechanical stress requirements, as well as packaging and handling protocols to avoid micro-fractures during transit.

Nantong Robuster Quartz Co., Ltd. is based in Haimen Industry Park, Nantong City, Jiangsu Province, China, and specializes in the production and export of fused quartz products. The company operates three ISO 9001:2008-certified factories, ensuring consistent quality across its product range, which includes fused quartz crucibles, fused silica ceramic labware, quartz tubes, and other quartz-based materials. Its portfolio covers 10-28 inch crucibles for semiconductor wafer manufacturing, 18-28 inch crucibles for the solar industry, and large-format crucibles for metallurgical sintering processes.

The supplier’s products comply with international standards and hold CE, RoHS, and REACH certifications, indicating adherence to environmental and safety regulations. With 80% of its output exported to Europe, the US, and Southeast Asia, the company emphasizes energy efficiency and resource conservation in its manufacturing processes.
