With good thermostability,insulation,temperature stability etc properties, 2 bores ceramic insulators tube are mainl used in B-type,S-type and new type tungsten-rhenium thermocouple sleeves.
With all the properties of 2 bores insulators tube,one-point two-temperature is also realizable in 4 bores ceramic insulatores tube.
All products through the German DIN standards: DIN43724 / DIN43725 /DIN40680
We only make high purity alumina ceramics
1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%.
2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.
3. Alumina is a refractory material, the higher the purity, the better the refractory effect
4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ºC ~ 1800 ºC.
5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.
6. High purity alumina has good hardness and good wear resistance.
7. High purity alumina products have a longer service life.
