In high-temperature industrial scenarios, traditional materials often experience performance degradation due to thermal expansion, oxidation, or chemical corrosion. However, the 1200 ℃ temperature resistant quartz rod, with its high-purity silicon dioxide (SiO ₂) material and precision manufacturing process, can maintain dimensional stability, chemical inertness, and transparency at extreme temperatures, becoming a core component in fields such as semiconductors, photovoltaics, and optical instruments.

FAQ：

What is the specific meaning of 1200 ℃ temperature tolerance?

A: Quartz rods can be used continuously for more than 24 hours in a high temperature environment of 1200 ℃ without softening, deformation, or chemical decomposition. The short-term peak temperature can withstand 1300 ℃.

Q2: What specifications are supported for customization?

A: The diameter range is 1mm-200mm, and the length can reach 3000mm. It supports surface treatments such as sanding, polishing, and coating, and can process irregular structures (such as hollow and threaded) according to the drawings.

Q3: What are the advantages compared to ordinary quartz rods?

A: High purity (≥ 99.99%) reduces impurity interference, low thermal expansion coefficient (5.5 × 10 ⁻⁷/℃) reduces the risk of thermal stress cracking, and light transmittance (UV to infrared band) reaches over 92%.

User core needs and problem solving

High temperature stability requirement: Solve the equipment shutdown problem caused by softening and deformation of traditional materials at high temperatures, and ensure continuous production.

Chemical corrosion resistance requirements: able to withstand all acidic and alkaline environments except hydrofluoric acid (HF), extend equipment life, and reduce maintenance costs.

Transparency requirements: Meet the high transparency requirements of optical instruments and laser systems, and improve signal transmission efficiency.

Dimensional accuracy requirement: tolerance control within ± 0.05mm, suitable for precision instrument assembly, reducing secondary processing costs.

Application scenarios and value

Semiconductor manufacturing: used for supporting heating chambers in high-temperature diffusion furnaces and oxidation furnaces to avoid metal contamination of wafers and improve yield.

Photovoltaic industry: As an insulation component for monocrystalline silicon growth furnaces, it can withstand the thermal radiation of molten silicon at 1200 ℃, ensuring the safety of the furnace structure.

Optical experiment: As a transparent window in a UV spectrometer, it can withstand high temperature disinfection environment to ensure data accuracy.

Aerospace: High temperature sensor protective cover for rocket engine nozzles, resistant to extreme thermal shock and oxidation corrosion.

Customer Application Cases

A leading European photovoltaic company once experienced a significant increase in maintenance costs for single crystal furnaces due to frequent cracking of traditional ceramic support rods at 1150 ℃. After switching to our customized 1200 ℃ quartz rod, the continuous operation cycle has been extended from 15 days to 90 days, saving over 2 million yuan in maintenance costs annually.
