5 FAQs of 95% 99%99.5% Al2O3 Alumina Insulated Ceramic Tube Pipe Bushing

Alumina Ceramic Tubes: Your Top 5 Questions Answered

What’s the difference between 95%, 99%, and 99.5% alumina?
The number shows the amount of aluminum oxide (alumina) in the ceramic. Higher purity means better performance. 99.5% alumina offers superior heat resistance and electrical insulation. 99% alumina provides excellent performance for most uses. 95% alumina is a good, cost-effective option for less extreme conditions.

How hot can these alumina tubes get?
Temperature limits depend on the purity. 95% alumina tubes typically handle continuous heat up to 1650°C. 99% alumina tubes manage about 1700°C. 99.5% alumina tubes withstand the highest temperatures, reaching 1750°C or even 1800°C. Exceeding these limits risks damage.

Why use alumina tubes for electrical insulation?
Alumina ceramic is an excellent electrical insulator. It doesn’t conduct electricity well. Its high dielectric strength prevents electrical breakdown. This property is crucial in high-voltage applications. The purity matters here too. Higher purity alumina offers better dielectric strength, often 15-20 kV/mm or more.

Are these alumina tubes physically strong?
Yes, alumina ceramic tubes are mechanically strong and hard. They resist wear and abrasion effectively. They handle sudden temperature changes well. This makes them durable in tough environments. Their strength increases with higher purity levels. 99.5% alumina is the strongest option available.

Where are these tubes commonly used?
These tubes are vital in high-temperature and electrical settings. You find them in furnace applications as thermocouple protection sheaths. They insulate heating elements. They act as bushings in electrical equipment. They serve in semiconductor processing equipment. Sensor protection is another key use. They work in kilns and lab equipment too.
