Alumina Ceramic Components For Thermocouple Protection Tubes And High-Temperature Furnace Plates In Industrial Heating
The alumina ceramic base is a high-purity aluminum oxide (Al₂O₃) ceramic component known for its excellent high-temperature resistance, corrosion resistance, electrical insulation, and mechanical strength. It is widely used in electronics, semiconductors, lasers, power systems, and chemical industries as a critical support or insulating element.
Electronic Packaging: Used as a heat dissipation and insulating substrate for high-power LEDs and integrated circuits.
Semiconductor Equipment: Functions as a wafer carrier or vacuum chamber component.
Laser Devices: Supports laser crystals or optical mirrors to ensure stability.
Industrial Heating: Serves as a high-temperature furnace plate or thermocouple protection tube.
✅ High-Temperature Resistance: Can withstand temperatures up to 1600°C.
✅ Excellent Insulation: Volume resistivity > 10¹⁴ Ω·cm.
✅ Corrosion Resistance: Resistant to strong acids and alkalis (except hydrofluoric acid).
✅ Low Thermal Expansion: Coefficient of thermal expansion (7.2×10⁻⁶/°C) matches most metals.
| Parameter | Specification |
|---|---|
| Material | 99% Al₂O₃ |
| Density | 3.8 g/cm³ |
| Flexural Strength | 300-400 MPa |
| Dielectric Constant | 9.8 (1MHz) |
| Surface Roughness | Ra ≤0.2μm (customizable) |
Powder Preparation: Mixing high-purity alumina powder with binders.
Forming: Dry pressing/isostatic pressing/injection molding.
Sintering: High-temperature densification at 1600-1800°C.
Precision Machining: CNC grinding/laser cutting to required dimensions.
Inspection: X-ray flaw detection, insulation strength testing.
⚠️ Precautions:
Avoid strong mechanical impacts to prevent brittle fracture.
Not suitable for hydrofluoric acid environments; recommended for pH 3-11 chemical conditions.
Use flexible gaskets to buffer stress during installation.
12-month warranty, free replacement for non-human damage.
24/7 technical support team.
Customizable dimensions and performance optimization available.
Q: Can complex shapes be machined?
A: Yes, CNC precision machining is supported, with a minimum hole diameter ≥0.5mm.
Q: What is the thermal conductivity?
A: Thermal conductivity is approximately 30 W/(m·K), better than standard stainless steel.
Q: Can it be metal-coated?
A: Yes, molybdenum-manganese metallization or magnetron sputtering is available.
