Product Name: 99% Alumina Double-Threaded Porous Crucible with Fine Holes & Lid
SKU: CX-AL-89001
Material: ≥99% Al₂O₃ (High-Purity Alumina)
🧪 Application
Designed for high-temperature experimental research and industrial thermal analysis, widely used in:
Materials science laboratories
Thermal testing & analysis systems
Industrial high-temperature processing
Research institutes & universities (USA / Europe / Asia)
♦️ Key Features
• Ultra-High Purity Alumina (≥99%)
Excellent thermal stability, mechanical strength, and outstanding chemical resistance in aggressive environments.
• Precision Forming Technology
Slip-casting manufacturing ensures high density and a smooth, uniform surface finish (inside & outside).
• Superior Thermal Resistance
Long-term working temperature: ≤1600°C
Sintering temperature: up to 1800°C
• Strong Chemical Stability
Resistant to corrosion from acids, alkalis, and reactive atmospheres.
• Functional Porous Design
Double-threaded structure with a fine porous lid enables controlled gas exchange for specialized thermal and experimental applications.
♦️ Usage Guidelines
Preheat at ~105°C for 120 minutes before first use to remove moisture
Avoid direct flame heating (e.g., acetylene, gasoline, alcohol flames)
Maintain ≥2 cm distance from heating elements (SiC rods, carbon tubes, wires)
Heating/cooling rate:
<5°C/min below 1200°C
<4°C/min above 1200°C
Use ceramic supports (e.g., corundum plates) to ensure airflow and extend service life
♦️ Global supply for laboratories, universities, and industrial R&D teams
