Product Description

Material & Quality

Made from 99.99% high-purity fused silica, our large-diameter quartz tube is free of impurities, ensuring minimal thermal expansion and maximum resistance to thermal shock (can withstand rapid temperature changes from -20℃ to 1200℃). It is non-toxic, non-porous, and resistant to most acids (except hydrofluoric acid) and alkaline solutions, making it suitable for corrosive chemical processing.

Core Advantages

Superior thermal stability: Operates continuously at 1100℃, short-term use up to 1450℃
Excellent mechanical strength: High compressive strength and impact resistance, cracking during installation and use
Customization support: Cut-to-length, flanged ends, and drilled holes available per customer drawings
Long service life: Resists aging and oxidation even under prolonged high-temperature exposure

Frequently Asked Questions

Q What is the dimensional tolerance for smaller substrate sizes like 10x10 and 20x20?

For smaller sizes such as 10×10, 20×20, and 30×30, the standard dimensional tolerance is kept tightly controlled at ±0.1.

Q What thickness options are available for the 50x50 size?

The 50×50 size comes in four standard thickness options: 1.0, 2.0, 3.0, and 5.0, with a thickness tolerance of ±0.08 to ±0.1.

Q How does the dimensional tolerance change as the size increases to 200x200?

As the size increases, the tolerance scales accordingly. For the largest size of 200×200, the dimensional tolerance ranges from ±0.3 to ±0.5.

Q What is the typical thickness tolerance for a 100x100 substrate?

For a 100×100 substrate, the standard thickness tolerance is ±0.1, with available thicknesses of 2.0, 3.0, and 5.0.

Q Are there ultra-thin options (like 0.5) available for larger dimensions?

According to the specifications, the ultra-thin 0.5 option is standard for smaller dimensions up to 20×20. For dimensions 30×30 and larger, the standard starting thickness is typically 1.0 or 2.0.
