The Quartz Furnace Tubes are core consumables in semiconductor manufacturing, photovoltaic industry, material heat treatment and laboratory research. They are made of high purity fused silica (SiO2) with excellent thermal stability, chemical inertness and optical transparency. This product is designed for high temperature processes (such as diffusion, oxidation, CVD, annealing, etc.), and can be adapted to a variety of tube furnaces and PECVD equipment, which are widely used in wafer processing, photovoltaic cell coating, LED epitaxial growth and other high-precision fields.


The core advantages of VET Energy quartz tubes:
-Ultra-high purity material
Adopting 99.99% or more high-purity quartz sand, impurity content (Na, K, Fe, etc.) <10ppm, to avoid contamination of sensitive process environment.
Surface finish Ra≤0.8μm, reducing particle adhesion and guaranteeing coating uniformity.
-Excellent temperature resistance
Long-term working temperature: 1200℃ (continuous use); short-term temperature peak: 1450℃ (≤2 hours).
Low thermal expansion coefficient (5.5x10-7/℃), excellent thermal shock resistance, can withstand rapid temperature rise and fall (≤10℃/min).
-Precise size control
Tolerance of inner diameter ±0.5mm, straightness error <1mm/m, to ensure a close match with the furnace body.
Support non-standard customization, inner diameter range 20mm-500mm, length 100mm-3000mm.
-Chemical inertness and corrosion resistance
Resistant to strong acid (except HF), strong alkali and most organic solvents, prolonging service life.
Excellent gas tightness, leakage rate <<1x10-9 Pa.m3/s, suitable for vacuum or protective gas environment.
-Customized service
Support openings, flanges, multi-channels, shaped structures and other designs to meet special process requirements.
Can be pre-plated with silicon carbide (SiC) coating to enhance crystallization resistance.
