Duralox 997 Ceramic Thermocouple Tubes - Jyoti Ceramic

 

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 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.

Duralox 997 Re-crystallized Alumina Ceramic is fine grained, non porous, dense and impervious to all acids except hydrofluoric acid. Duralox 997 is exceptionally high purity Alumina Ceramic, containing 99.7% Al2O3 and SiO2 less that 0.05% in its residue.



Physical Strength : Duralox 997 Alumina is extremely hard with high mechanical strength and resistant to abrasion & corrosion and good thermal conductor at high temperatures.

Imperviousness : Duralox 997 Alumina products are fired at extremely high temperature around 1750 0C which ensures impermeability under severe & critical conditions.

Good Electrical Resistivity : Duralox 997 Alumina maintains good electrical resistivity at high temperatures.

High heat Conductivity : Duralox 997 Alumina products are considered as high-tech products and are manufactured with advanced technology, therefore maximum density is ensured with minimum wall thickness. This makes the highest possible heat transfer.

Stability at high temperature and chemical Inertness : Duralox 997 is inert even at high temperatures in reducing atmosphere and flux attack due to low silica content in its residue.

Product Range : Duralox 997 Alumina product range includes Ceramic thermocouple tubes with Closed One End (COE), Open Both Ends (OBE), tubes with Single and Multibores, Thin-wall tubes, Capillary tubes, Round and Oval rods above Ø 0.5 mm.

Amphoteric : Duralox 997 Alumina is highly resistant to acid slugs.

Ceramic thermocouple tubes and Multibore tubes other than above sizes can be manufactured on request.

Duralox 997 Alumina Ceramic Thermocouple Tubes & Multibore tubes are formed by high pressure extrusion, dry/wet bag isostatic pressing.

We are constantly working for improvement of the product quality, hence the data given in the brochure may change as and when found necessary.
