Abstract of Sapphire tubes
ZMSH specializes in supplying unpolished sapphire tubes manufactured from ultra-high purity alumina (Al₂O₃ ≥99.99%) using either the Kyropoulos (KY) method or Edge-defined Film-fed Growth (EFG) method to produce high-quality single crystals, followed by precision machining. Our products are available in various diameters ranging from Φ5mm to Φ150mm, with customizable wall thicknesses (0.5-20mm) to meet stringent requirements across semiconductor, optoelectronic, and industrial equipment applications.
With over 10 years of expertise in crystal growth and precision machining, we maintain a monthly production capacity exceeding 5,000 pieces. We reliably supply rough blanks and support subsequent precision processing (including CNC cutting, high-precision drilling, end-face grinding, etc.). Future R&D will focus on optimizing manufacturing processes for large-diameter sapphire tubes (Φ200mm+) and improving cost efficiency to expand applications in high-end markets such as semiconductor equipment, laser optics, and new energy.
• Exceptional Hardness (Mohs 9): Second only to diamond, sapphire tubes offering excellent wear resistance for high-friction environments.
• Outstanding Thermal Resistance: Unpolished sapphire tubes withstands extreme temperatures up to 2050°C while maintaining excellent thermal shock resistance for rapid temperature variations.
• Chemical Inertness: Unpolished sapphire tubes demonstrates superior resistance to strong acids (e.g., HF), alkalis, and plasma corrosion, making it ideal for semiconductor etching processes.
• Optical Performance: Maintains >80% light transmittance in the visible spectrum (400-700nm) even in unpolished state, suitable for certain optical applications.
• Mechanical Strength: Features flexural strength >400MPa and compressive strength >2GPa, making it suitable for high-pressure and high-stress environments.
1. Semiconductor Equipment:
• Plasma etching chamber liners: Corrosion and plasma erosion resistance extends equipment lifespan.
• Wafer processing observation window substrates: Sapphire tubes high transmittance and heat resistance ensure clear process monitoring.
2. Industrial Windows:
• High-temperature furnace viewing tubes: Sapphire tubes Stable operation in environments exceeding 1800°C.
• High-power laser equipment protective sleeves: Thermal shock resistance prevents laser scattering damage.
3. Optoelectronic Components:
• UV/IR sensor protective sleeves: Combine high transmittance with environmental resistance.
• Optical system blank components: Serve as substrates for subsequent precision polishing or coating.
4. Scientific Instruments:
• Extreme environment experimental devices (e.g., ultra-high pressure, intense radiation): Sapphire tubes provide reliable consumable solutions.
As a leading domestic sapphire material supplier, ZMSH focuses on the R&D and production of unpolished sapphire tubes, offering one-stop services from crystal growth and blank processing to customized precision forming. Our proprietary manufacturing technology ensures industry-leading performance in key parameters including crystal purity (<10ppm impurities) and dislocation density (<10³/cm²).
Customized ruby products:
1. Q: What are the primary applications of sapphire tubes?
A: Sapphire tubes are widely used in semiconductor manufacturing (e.g., plasma containment, thermocouple protection), medical devices (e.g., laser surgical tools), optical systems (e.g., UV/IR lamp envelopes), and high-pressure industrial equipment (e.g., chemical reactors) due to their extreme durability and transparency .
2. Q: Why choose sapphire tubes over quartz or ceramics?
A: Sapphire tubes outperform quartz and ceramics in high-temperature stability (up to 2000°C), chemical inertness (resists acids/alkalis), and mechanical strength, making them ideal for harsh environments like plasma processing and aerospace systems .
