Duralox 997 Recrystallized Alumina Ceramic Thermocouple Tubes

Duralox 997 Ceramic Pyrometry Tubes

Duralox stands for durable Aluminium Oxide and is a registered trade name of Jyoti Ceramic Industries Pvt. Ltd. It stands for Aluminium Oxide ceramic compositions containing 90 to 99.7% & above percentage of Al2O3 in its residue.

Pyrometry Sheaths

The main feature of Duralox 997 Re-Crystalized Alumina is its very high degree of chemical inertness, it offers a high degree of protection against reactive slags or furnace gasses and its low silica content ensures that there is no contamination of rare metals such as platinum by silicon a frequent cause of loss of calibration in thermocouples.

Tubes

Duralox 997 re-crystallized Alumina ceramic thermocouple tubes pass good electrical resistivity as well as high thermal conductivity at high temperatures. When supported adequately, they can be used up to a temperature of 1800 0C + (3272 0F) and are suitable for molybdenum and tungsten wound tube furnaces, particularly for processes requiring a tube of an impervious nature.

Single and Multibore Insulators

Duralox 997 Re-crystallized Alumina can be used up to a temperature of 1800 0C. It is particularly suitable for use as an insulator for rare metal thermocouples, because of its extremely low silica content ; it ensures that there is no contamination of rare metals such as platinum with silicon. Duralox 997 alumina closed one end Ceramic Thermocouple Tubes or Single and Multibore Tubes are sintered vertically at approximately 1750 0C temperature, in oxygen atmosphere in microprocessor controlled bell type kiln. After sintering, 100% thermocouple tubes are tested under air pressure @ 4 bar to ensure gas tightness.

Advantages

Duralox 997 Re-crystallized Alumina Ceramic offers following advantages over the metals :


  • Continuous high-temperature resistance 17500C.
