In the field of modern materials science, alumina ceramic tubes hold a pivotal position due to their exceptional performance and wide-ranging applications. Their unique physical and chemical properties drive technological advancements across numerous industries.

I. Characteristics of Alumina Ceramic Tubes

(1) Outstanding Mechanical Properties

Alumina ceramic tubes exhibit extremely high hardness, with a Mohs hardness rating of 8–9, far surpassing the wear resistance of many metals. For example, in oil drilling, slurry transport pipes made of alumina ceramic withstand high-speed particle erosion, significantly extending service life. Additionally, their excellent compressive strength ensures stable operation in high-pressure environments, such as high-pressure gas delivery systems.

(2) Superior Chemical Stability

These ceramic tubes demonstrate strong corrosion resistance against most acids, alkalis, salts, and other chemical media. Whether in strong-acid chemical production or high-alkaline industrial wastewater treatment, their chemical stability prevents corrosion. This makes them highly favored in chemical and environmental industries, ensuring long-term equipment reliability and reducing maintenance costs.

(3) Excellent High-Temperature Resistance

Alumina ceramic tubes maintain structural and performance stability at high temperatures, enduring up to 1600°C or even higher. In steelmaking furnaces, they serve as high-temperature gas delivery pipelines or structural components, adapting to harsh thermal environments and enhancing production efficiency.
