SCERAM has been distributing ceramic tubes and quartz tubes for furnaces for more than four decades and stocks Alumina tubes, Quartz tubes, as well as Mullite tubes in porous and impervious versions for easy and quick delivery. SCERAM also provides small quantities of tubes in high purity Alumina (99,7%) and Mullite C610 for the maintenance of heat treatment furnaces and laboratory furnaces. The Alumina 99,7% is certified for high vacuum furnaces with no degassing.

SCERAM offers a number of standard ceramic tubes, such as ceramic tubes (Figure 1), ceramic tubes with bores, ceramic one-end closed tubes, and insulating beads. The company also offers the following tubes:
- Alumina 99,7% tubes
- Quartz tubes
- Impervious Mullite C610 tubes
- Porous Mullite C530 tubes
- Zirconia Oxide tubes
- Silicon Carbide recristalized tubes
- Silicon Carbide infiltrated tubes.
Basic Properties of Ceramic Tubes
The Alumina 99,7% tubes are very hard and can be milled and polished with high precision. The tubes are resistant to abrasion and corrosion and are stable at high temperatures. They are chemically inert and have excellent electrical properties.
The Quartz tubes have low coefficient for thermal expansion, high chemical purity, high thermal shock resistance, and excellent optical properties. The tubes can be shaped in molten form and thus allows for complex shapes. They can be welded easily and have good UV transmission.
The Mullite C610 tubes have high temperature resistance, high refractoriness, and good electrical insulation, while the Mullite C530 tubes are porous, have high temperature resistance, high thermal shock resistance, and high refractoriness.
The Zirconia Oxide tubes have high temperature resistance, high mechanical properties, and low thermal conductivity. The tubes can be used at 2200°C under nitrogen.
The Silicon Carbide recristalized tubes are porous and have good mechanical resistance even at high temperature. They have excellent dimensional stability and resistant to thermal shocks, acids and alkalis. The Silicon Carbide infiltrated tubes share similar properties like the Silicon Carbide recristalized tubes and are available in big-sized components.
SCERAM distributes a variety of ceramic tubes and quartz tubes. These tubes are impervious to thermal shocks, acids and alkalis, and have excellent mechanical and temperature resistance.
