High Purity Alumina Ceramic Tubes
My factory looking for distributors.
Advantages of High Purity Alumina Ceramic Tubes
High purity alumina ceramic tubes offer exceptional performance and versatility across a wide range of applications due to their unique properties and composition. With a purity level of 99.3% , alumina ceramic tubes exhibit superior strength, thermal stability, and resistance to corrosion, making them ideal for demanding industrial and scientific environments.
Applications of High Purity Alumina Ceramic Tubes
1. Alumina ceramic tubes find extensive use in semiconductor manufacturing processes.
2. Alumina ceramic tubes are an ideal choice for protecting thermocouples in high-temperature environments.
3. Alumina ceramic tubes are commonly used in laboratory equipment.
Cleaning method for alumina ceramic tubes
Method 1: Clean with clean water
The surface of alumina ceramic tubes is smooth and will not hide many other substances during use. It can be gently cleaned with clean water.
Method 2: Use tools to rinse
For a alumina ceramic tube, because it is very wear-resistant, it can also be cleaned with some high friction coefficient cleaning tools.
Method 3: Ceramic detergent or soap
If alumina ceramic tube is very dirty, you can buy ceramic detergent or soap at this time. As long as you use the cleaning agent and water together, you can quickly wash away those dirty things.

Our factory
Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
FAQ
A1: We are factory.
A2: Generally it is 5-10 days if the goods are in stock. Or it is 15-30 days if the goods are not in stock, it is according to quantity.
A3: Yes, we could offer the little sample for free charge but do not pay the cost of freight.
