Small and short quartz rods

In the fields of precision instruments, semiconductor processing, and optics, small-sized and short quartz rods have become an ideal choice for key components due to their high purity, high temperature resistance, and excellent optical performance. This type of quartz rod typically has a diameter between 0.5mm-10mm and can be customized in length as needed. It can meet micron level machining accuracy and adapt to extreme environments such as high temperature and strong corrosion. It is an indispensable basic material in scientific research experiments and industrial production.

FAQ: Frequently Asked Questions for Users

Q1: How to ensure the purity of small-sized quartz rods?

A: We use high-purity natural quartz sand (SiO ₂ content ≥ 99%), remove impurities through vacuum melting process, and produce the entire process in a clean workshop to ensure that each batch of products meets the standards.

Q2: What is the minimum size that can be customized?

A: The diameter supports a minimum order of 0.3mm, and the length can be precise to the 0.1mm level. It also supports deep processing services such as irregular cross-sections (such as square and hexagonal) and end face polishing and chamfering.

Q3: Will it deform under high temperature conditions?

A: Quartz rods can withstand temperatures up to 1200 ℃ and short-term use up to 1500 ℃. Their thermal expansion coefficient is only 3.3 × 10 ⁻⁷/℃, and they can still maintain dimensional stability in high-temperature environments.

User core needs and product value

Solving the problem of miniaturization design: small-sized quartz rods can be embedded in micro sensors, endoscopes, and other devices, helping to reduce the weight and integrate products.

Dealing with extreme environmental challenges: acid and alkali resistant, radiation resistant, suitable for high corrosion or strong radiation scenarios such as semiconductor etching and laser resonators.

Reduce overall costs: High transmittance (over 92%) reduces light energy loss, prolongs equipment life, and has significantly better cost-effectiveness than ordinary glass for long-term use.

Application scenarios and advantageous value

Semiconductor manufacturing: As a support column for wafer carriers, the high purity of quartz rods avoids metal ion contamination and improves yield.

Optical instruments: used as light guiding components for spectrometers and microscopes, with low dispersion characteristics to ensure imaging clarity.

Medical equipment: The quartz light guide rod inserted into the endoscope tube is resistant to high temperature disinfection and has uniform light transmission, improving diagnostic accuracy.

Research experiment: High temperature furnace observation window bracket, heat-resistant impact performance ensures experimental safety.

Customer Application Cases

Case 1: A European semiconductor equipment supplier

The customer needs to customize a quartz rod with a diameter of 2mm and a length of 50mm for a 12 inch wafer transfer arm. We successfully replaced the original Japanese supplier and reduced costs by 30% by adjusting the melting temperature and drawing speed to control the straightness within ± 0.02mm.

Case 2: A leading laser enterprise

The customer requests that the parallelism of the quartz rod end face be ≤ 5 arc seconds to reduce laser coupling losses. We use CNC polishing machines and online detection systems, and the final product has a parallelism of 3 arc seconds, helping customers improve laser power stability to 99.5%.
