Government-Endorsed R&D Projects
Demonstrated engineering competence through provincial and national high-tech manufacturing initiatives.
Jiangsu Provincial S&T Project
Our Ø320 mm high-purity quartz diffusion tube designed for large-scale integrated circuit (LSI) wafer processing was officially qualified under the Jiangsu Provincial Science and Technology Support (Industrial) Project, confirming ultra-low bubble density and structural durability under sustained 1,150°C heat.
National New Product Qualification
Our newly engineered Ø520 mm large-diameter high-purity quartz pipe successfully passed the preliminary evaluation of National New Products. This technology enables next-generation high-throughput thermal processing vessels with tight geometrical tolerances.
Wafer Furnace Transformation Fund
VEZLO Quartz has systematically mobilized the Jiangsu Special Fund for the Transformation of Scientific and Technological Achievements to industrialize large-bore quartz furnace tubes engineered for 14-inch-plus wafer oxidation and diffusion processes.
Engineered Quartz Product Portfolio
Manufactured in strict conformance with ASTM, SEMI, and ISO glass standards for discerning global buyers.
Fused Quartz Tubing (OD 2–500 mm)
Clear transparent silica tubes, ozone-free doped tubes (185nm cutoff), UV-transmitting sleeves, and heavy-wall heating pipes cut and fire-polished to exact drawings.
Semiconductor Quartzware
Horizontal and vertical diffusion furnace core tubes, wafer carrier boats, slotted quartz cages, multi-wafer supports, and CNC-machined quartz flanges.
Quartz Plates, Sheets & Sight Windows
JGS1, JGS2, and JGS3 optical-grade quartz substrates with double-side commercial or laser-grade polishing, bevelled edges, and custom hole-drilling.
Transparent Crucibles & Lab Apparatus
Thermal-shock-proof transparent crucibles for precious metal smelting, ash analysis, along with quartz beakers, flasks, and acid-resistant cleaning tanks.
Quartz Glass Rods (Ø1.5–80 mm)
Precision-drawn solid quartz rods and light guides featuring exceptional optical homogeneity, low bubble density, and high linear transmission.
Ultra-High Purity Sand & Coating Granules
13 grades of beneficiated natural quartz sand (≤20 ppm total metal impurities) and amorphous quartz coating particles for optical thin-film vacuum deposition.
