Specifications of High Purity 99.7% Al2O3 Alumina Ceramic Tube for Furnace

This alumina ceramic tube is extremely pure. It includes 99.7% Al2O3. This high purity matters. It offers the tube exceptional performance in difficult furnace problems. The material withstands chemical attack well. It stays steady under high warmth.

The tube comes in typical sizes. Usual outside sizes range from 10mm to 150mm. Wall thicknesses are typically in between 3mm and 20mm. Sizes can reach 2000mm or more. Custom-made sizes are feasible. We can make tubes to fit your specific heating system design.

Temperature level resistance is essential. This tube takes care of continuous consume to 1700 ° C. Short ruptureds to 1800 ° C are alright. The product does not melt easily. It keeps its form under extreme heat. Thermal shock resistance is good. Television deals with quick heating or cooling cycles.

Thickness is high. It measures over 3.85 g/cm THREE. This thick structure makes television solid. It withstands wear efficiently. Surface area finish is smooth. This reduces friction. Television is very difficult. It ratings around 9 on the Mohs range. Electrical insulation residential or commercial properties are outstanding. Television does not perform electrical power.

Mechanical strength is impressive. Television endures hefty lots. Its bending stamina is high. The product withstands creep. It preserves dimensions under stress and anxiety and heat. This tube works in air or inert environments. It carries out accurately in vacuum heaters as well.

Normal uses are heating system linings, thermocouple protection sheaths, and procedure tubes. It carries gas or holds examples. Television is suitable for sintering, annealing, and warm treatment processes. Its purity protects against contamination. It ensures consistent, high-quality results.

Applications of High Purity 99.7% Al2O3 Alumina Ceramic Tube for Furnace

High purity 99.7% Al2O3 alumina ceramic tubes are important components in demanding heating system operations. Their extraordinary buildings make them perfect for high-temperature settings. These tubes stand up to temperatures going beyond 1700 ° C accurately. This security is important for consistent furnace efficiency. They stand up to thermal shock efficiently. Abrupt temperature changes will not conveniently fracture them. This durability guarantees lengthy life span. It minimizes furnace downtime dramatically.

Chemical inertness is an additional major benefit. Televisions withstand attack from the majority of molten metals, salts, and corrosive gases. This prevents contamination of delicate materials inside the furnace. Test pureness is kept throughout processing. Heater ambiences remain cleaner. Maintenance intervals become much longer.

Electric insulation is exceptional. Alumina tubes don’t carry out electrical power. This makes them ideal for shielding burner or thermocouples. They stop electrical shorts safely. Accurate temperature dimension is feasible. Trusted heater control outcomes.

These tubes are widely used for thermocouple defense. They secure delicate sensors from extreme heater conditions. Temperature analyses stay exact. They function as safety sheaths for heating elements. Element life expands. Heating system effectiveness enhances.

Taste containment is an additional key use. The tubes hold products throughout sintering or warmth therapy. Contamination risks are minimized. They function as burning tubes. Samples melt totally inside regulated atmospheres. They function as procedure tubes for semiconductor crystal growth. Extreme pureness is necessary here. Our 99.7% Al2O3 delivers that.

The smooth surface finish protects against product sticking. Cleaning up is uncomplicated. Tube honesty remains high cycle after cycle. Regular dimensions make sure simple furnace assimilation. Very little modifications are needed throughout installment.

5 FAQs of High Purity 99.7% Al2O3 Alumina Ceramic Tube for Furnace

What is this alumina ceramic tube?
It’s a tube made from 99.7% pure aluminum oxide. This high purity makes it very strong. It resists extreme heat and chemicals well. It’s mainly used inside furnaces and high-temperature equipment.

How hot can this tube get?
It handles temperatures up to 1700°C (3092°F) easily. This makes it perfect for furnace linings, thermocouple protection, and similar hot jobs. It won’t melt or weaken at these temperatures.

Why pick this over other materials?
Alumina ceramic beats metals and plastics in heat. Metals corrode or melt. Plastics burn. This tube stays strong. It doesn’t wear out fast. It keeps its shape under heat stress. This means less replacing parts. It saves money over time.

What sizes are available?
You find many sizes. Common outside diameters are 3mm to 150mm. Lengths often go up to 2000mm. Wall thickness varies too. Custom sizes are possible. Check the supplier’s list for exact options.

How careful must I be handling it?
Handle it gently. Alumina ceramic is very hard. It resists scratches. But it can crack if hit hard or dropped. Avoid sudden temperature changes. Let it heat up and cool down slowly. This prevents thermal shock damage. Store it safely away from knocks.
