Specification of 99% Al2O3 High Purity Alumina Ceramic Tube for Tube Furnace

This alumina ceramic tube is made from 99% pure Al2O3. It is created for demanding tube heating system applications. High pureness implies minimal contaminations. This guarantees outstanding chemical security. The tube withstands attack from lots of aggressive chemicals and gases. It carries out well under high-temperature conditions. The maximum continuous operating temperature reaches 1750 ° C. Short-term use can manage also greater levels. Thermal shock resistance is excellent. Television handles quick temperature adjustments efficiently. This protects against breaking during home heating or cooling cycles.

Mechanical strength is high. The tube supplies strong bending resistance (flexural toughness). It stands up to significant physical stress and anxiety. Hardness is phenomenal. The product resists wear and abrasion quite possibly. Electrical insulation homes are impressive. Television dependably isolates electrical elements. Dielectric strength stays high even at elevated temperatures. Dimensional accuracy is precise. Tubes are made to limited resistances. This makes sure an appropriate fit within heating system settings up. Smooth inner and outer surface areas reduce gas circulation resistance. The surface area finish protects against particle trapping. Surface roughness is usually very reduced (Ra worth). Television supplies a clean atmosphere for procedures. Usual dimensions are offered. Standard lengths and sizes match most furnace layouts. Customized measurements are likewise feasible. This tube dependably has examples and ambiences. It maintains pureness vital for delicate job.

Applications of 99% Al2O3 High Purity Alumina Ceramic Tube for Tube Furnace

High pureness alumina ceramic tubes made from 99% Al2O3 are important parts for tube furnaces. This material provides superb performance under extreme problems. Its high pureness means it manages very heats well. Tubes stay secure and solid also over 1700 ° C. This makes them reliable for long heating system runs. They resist wear and tear properly.

Thermal shock resistance is another crucial advantage. These tubes deal with sudden temperature level changes without splitting. This is very important throughout fast heating or cooling down cycles. The material likewise shows solid chemical resistance. It withstands destructive gases and reactive atmospheres inside furnaces. This protects sensitive examples from contamination. So the tube itself doesn’t hinder experiments.

Electric insulation is critical too. The alumina tube serves as a solid insulator. This stops electric currents from creating issues. It maintains heating system operations safe and controlled. This is crucial for procedures needing electrical seclusion.

These residential properties make 99% Al2O3 tubes perfect for a number of demanding tube heating system makes use of. They are excellent for sintering sophisticated ceramics. The tube gives a tidy, high-temperature setting. This is essential for accomplishing dense, strong ceramic parts. Metal powder handling also benefits. The tube securely contains metal powders during heat treatment. This ensures constant outcomes.

Growing single crystals needs severe stability. The alumina tube provides this. It preserves exact conditions needed for crystal growth. Slim movie deposition processes like CVD rely upon these tubes. They provide a chemically inert surface area. This protects against unwanted responses throughout covering. Warmth treating sensitive materials needs pureness. Television avoids contamination of semiconductors or fiber optics. Annealing glass or steels requires dependable containment. The alumina tube supplies this under high warmth.

Compared to quartz tubes, alumina withstands a lot higher temperatures. It also stands up to chemical assault far better. This makes it the leading option for advanced, high-performance tube heater work.

5 FAQs of 99% Al2O3 High Purity Alumina Ceramic Tube for Tube Furnace

5 FAQs: 99% Al2O3 High Purity Alumina Ceramic Tube for Tube Furnace

1. What’s the highest temperature this tube handles?
This tube handles continuous use up to 1700°C (3092°F). Short bursts might reach 1800°C (3272°F). We recommend staying below 1650°C (3002°F) for best long-term life. Going too high causes damage. Always check your specific furnace specs.

2. Why does 99% purity matter?
Higher purity means better performance. It gives superior resistance against heat. It gives better resistance against chemicals. It gives better resistance against wear. Impurities weaken the material. They make it crack sooner. They make it react badly with samples. This purity ensures cleaner, more stable furnace conditions.

3. How careful do I need to be handling it?
Handle it very carefully. Alumina ceramic is hard but brittle. Sudden knocks or drops cause cracks. Uneven heating stresses it. Always support the tube evenly. Avoid any sharp impacts. Use gloves to prevent skin oils. Check for damage before each use.

4. How do I clean it properly?
Cleaning needs care. Avoid harsh chemicals. Avoid abrasive scrubbing. Use mild detergents with soft cloths or brushes. Rinse thoroughly with pure water. Let it dry completely before heating. Thermal shock cracks a wet tube. Never cool it rapidly.

5. Can I get a custom size or shape?
Yes, custom sizes are possible. We make tubes to your furnace dimensions. Standard diameters and lengths are common. We also make special end shapes. Provide your exact requirements early. Custom orders take more time. They cost more than standard stock items.
