My factory looking for distributors.


Alumina ceramic tubes have a wide range of applications, involving high-temperature testing and analysis equipment in various industries, such as coal testing and analysis equipment, metallurgical powder testing and analysis equipment, and chemical and glass industry testing and analysis equipment.

Our alumina ceramic tubes are exported to more than 30 countries. The quality of our products is deeply liked by customers. Crucible products are also purchased by many university laboratories and mining laboratories. Parts products are also ordered by many large machine companies.

Alumina Ceramic


We only make high purity alumina ceramics

1. High-purity alumina content 99.3% -99.5%, other alumina ceramic92% -99%.
2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.
3. Alumina is a refractory material, the higher the purity, the better the refractory effect
4. After high-purity
alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ℃ ~ 1800 ℃.
5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.

6. High purity alumina has good hardness and good wear resistance.
7. High purity alumina products have a longer service life.

RFQ

1.Is alumina a good thermal insulator?

Alumina (Al2O3) is a widely used material for highly insulating films due to its very low electrical conductivity, even at high temperatures.

2.What are the uses of alumina tube?

In more cutting-edge industries, alumina tubes are widely used as components in hi-tech process equipment. Applications include: Parts for CVD, ion implants, photolithography, and semiconductor systems. A high voltage insulator in plasma cleaning systems for aluminum rolling and coating mills.

3.Is alumina flammable?

Not combustible. In case of fire in the surroundings, use appropriate extinguishing media.

4.Why use alumina instead of silica?

Of all the metal oxides, alumina performs best in this role as an amphoteric ion exchanger. In comparison the more commonly used silica only allows for a cation exchange due to its low pH pzc. Alumina is stable. It overcomes the relatively low and high pH instability of silica.
