Ceramic tubes are typically used in applications where resistance to corrosion or thermal stability is a requirement. This could be for example, in the Chemical & Process or molten metal handling industries or in thermal applications.

In the chemical & process industries, the handling and movement of often very corrosive chemicals requires materials with excellent chemical stability. Traditionally, metals such as inconel have been used. However, in many applications inconel has a limited life. International Syalons manufacture sialon and silicon carbide tubes, which have outstanding chemical stability and in many cases last significantly longer than inconel.

In non–ferrous molten metal handling, the use of Syalon thermocouple protection sheaths and heater and riser tubes demonstrate the material's excellent thermal and chemical behaviour.

Advanced ceramics are characterised by high melting points and thermal stability. For example, alumina has a melting point of 2050°C. Alumina tube is typically used as a thermocouple protection sheath or as a support for kiln insulation.
