20-50mm small size transparent fused silica slotted rod
The 20-50mm small size transparent fused silica slotted rod is a special glass rod made from high-purity silicon dioxide (SiO ₂ content ≥ 99.95%) by high-temperature plasma melting process.
The core features include:
High temperature resistance: The softening point temperature can reach 1730 ℃, and it can be used for a long time at 1100 ℃. The short-term temperature tolerance can reach up to 1450 ℃, making it suitable for high-temperature processing environments.
Chemical stability: Except for hydrofluoric acid, it hardly reacts with any acid, and its acid resistance is 30 times that of ceramics and 140 times that of stainless steel, ensuring long-term stability in highly corrosive environments.
The coefficient of thermal expansion is extremely low: only 1/10-1/20 of ordinary glass, and can withstand drastic temperature changes (such as being heated to 1100 ℃ and directly put into cold water without exploding), avoiding cracking caused by thermal stress during processing.
Optical Transparency: With a transmittance of over 99%, it supports full band light transmission from ultraviolet to infrared, meeting the stringent requirements of optical systems for material purity.
Typical application scenarios:
A slot rod used as a chip carrier boat in semiconductor manufacturing, for chip insertion positioning in oxidation diffusion processes;
Structural support components in the production of fiber optic preforms to ensure uniform drawing of optical fibers;
The optical window or reflector substrate in laser technology can withstand long-term exposure to high-energy laser beams.
Core application area: the "precision key" to solve industry pain points
1. Semiconductor industry: improving chip processing yield
Background of the problem: In the semiconductor oxidation diffusion process, the slot bars of traditional quartz boats are prone to chip insertion displacement due to insufficient positioning accuracy, causing uneven diffusion on the silicon wafer surface and resulting in a decrease in yield.
Solution:
This product achieves millimeter level positioning accuracy through V-shaped clamping block centering technology, ensuring that the slot spacing error is ≤ 0.02mm;
The surface smoothness reaches Ra ≤ 0.05 μ m, reducing friction damage between the chip and the groove rod;
Support multi angle slotting (such as 0 °, 90 °, 180 ° rotation positioning) to meet different process requirements.
Case: After a 12 inch wafer fab adopted this product, the chip insertion offset rate decreased from 0.3% to 0.05%, saving over 2 million yuan in annual rework costs per line.
2. Fiber optic communication: ensuring the stability of optical signal transmission
Background of the problem: In the production of fiber preform rods, traditional quartz rods suffer from increased optical loss due to bubbles and gas line defects, which affect the bandwidth performance of the fiber.
Solution:
Using plasma melting technology, the internal bubble content of the material is ≤ 0.001%, and the gas line density is ≤ 0.5 strips/cm;
The curvature should be controlled within 3 ‰ of the total length to avoid fiber breakage caused by deformation of the rod during the drawing process;
Support customized gradient sizes of 1-50mm diameter to match different fiber drawing equipment.
Case: After a certain fiber optic enterprise used this product, the fiber attenuation coefficient decreased from 0.22dB/km to 0.18dB/km, reaching the international leading level.
3. Laser technology: extending the service life of equipment
Background of the problem: In high-energy lasers, traditional mirror substrates are prone to deformation due to their high coefficient of thermal expansion, resulting in beam deviation during long-term use.
Solution:
The coefficient of thermal expansion is as low as 0.5 × 10 ⁻⁷/℃, close to zero expansion materials (such as Corning 7971 quartz from the United States);
Excellent radiation resistance, able to withstand gamma rays above 10 ⁶ Gy without discoloration;
Support coating processes (such as anti reflective films and high reflectivity films) to enhance the energy tolerance threshold of optical components.
Case: After a certain laser processing center adopted this product, the replacement cycle of the reflector was extended from 6 months to 3 years, and the comprehensive utilization rate of the equipment increased by 40%.
