49×25×5 High Purity Quartz Sleeve Can Customizable Size

Product Name: High Purity Quartz Sleeve
Dimension: Outer Diameter Φ49mm, Inner Diameter Φ25mm, Wall Thickness 5mm; outer diameter, inner diameter, length and wall thickness are customizable as required

Precision machined from integrated high-purity quartz tube, featuring high temperature resistance, resistance to hydrofluoric acid and concentrated acids and alkalis, high light transmittance and zero metal ion precipitation. It is widely applied as insulating protective sleeves for high-temperature furnaces, shaft protection sleeves for equipment, isolation parts for semiconductor coating chambers, inner liners for laboratory high-temperature reactors, protective fittings for lithium battery high-purity fluid delivery and positioning sleeves for optical instruments. It separates high-temperature heat sources from metal components to avoid corrosion and contamination, and supports visual light path observation, suitable for high-temperature processes of photovoltaic, fine chemical, microelectronics and new energy industries.

1. Excellent High Temperature Resistance and Thermal Stability: Stable long-term service at 200℃–1100℃, crack-proof under rapid temperature alternation.

2. Superior Corrosion Resistance: Withstand long-term erosion of hydrofluoric acid, concentrated strong acids and alkalis, irreplaceable by metal and ordinary ceramics.

3. Ultra-High Cleanliness without Impurity Precipitation: High-purity quartz substrate with no heavy metal leaching, preventing contamination to wafers, electrolytes and high-purity chemical reagents.

4. Good Optical Transmittance: High permeability to ultraviolet and visible light for direct observation of internal reaction conditions.

5. Precision Dimensional Machining: High concentricity of inner and outer circles with smooth surface and uniform assembly clearance; secondary processing including cutting, slotting and polishing is available.
