Product Specification

1. Basic Product Information

Product Name: S1 High Purity High Temperature Resistant Quartz Tube Dimension: Outer Diameter Φ44mm × Inner Diameter Φ34mm × Total Length 230mm

2. Main Applications

This S1 quartz tube is integrally melted from high-purity quartz raw material, featuring high temperature resistance, outstanding thermal stability, low impurity precipitation and excellent light transmittance. It is widely applied to high-temperature and ultra-clean working conditions in various industries.

(1) Laboratory Tube Furnace

Carrier for High-Temperature Sintering & Calcination Serves as standard furnace tube for calcination, thermogravimetric analysis and atmosphere sintering of powder samples. Protective gas such as nitrogen, argon and hydrogen can be filled to isolate air and prevent sample oxidation and contamination. Cavity for Gas-Phase Pyrolysis & Catalytic Reactions Applied in high-temperature gas-solid catalysis and thermal cracking tests. No metal ions leach from tube wall to interfere component testing, allowing real-time visual observation of reactions.

(2) Semiconductor & PV Microelectronics

Liner Tube for Diffusion & Oxidation Furnace Used for high-temperature oxidation and doping diffusion of wafers. High-purity substrate avoids heavy metal contamination on silicon wafers, ensuring electrical performance and yield of electronic devices. Transmission Pipeline for High-Purity Electronic Gas Conduit for special electronic gas delivery, resistant to corrosive clean media and suitable for ultra-clean microelectronics manufacturing.

(3) Lithium Battery New Materials & Fine Chemicals

High-Temperature Purification of Powder & Calcination of Precursors Carrier for atmosphere calcination of lithium battery cathode/anode materials and high-purity chemical powder. Resistant to acid-base atmosphere erosion without impurity precipitation affecting material purity. Protective Sleeve for High-Temperature Synthesis Inner liner for corrosive gas-phase synthesis processes, replacing borosilicate glass and ceramic tubes; no pulverization or leakage under long-term high temperature service.

(4) Photocatalysis, UV Curing & Special High-Temperature Working Conditions

Transparent Cavity for UV Reactions High transmittance in UV and visible light bands, suitable for photocatalytic degradation, UV aging irradiation and photochemical reaction equipment. Continuous High-Temperature Heat Treatment Stably operated at 200℃-1100℃ long-term, excellent thermal shock resistance against sudden cold-hot alternation, matching continuous high-temperature gasification and heat treatment production lines.
