Long Zirconia Thermocouple Protection Ceramic Tube

Long Zirconia Thermocouple Protection Ceramic Tube

The specification of advanced ceramic tube

The main features of zirconia thermocouple protection ceramic tube

1. Much higher density than most of technical and advanced ceramics, over than 6 g/cm3

2. Excellent wear and abrasive resistance, much higher 276 times than stainless steel

3. Various complicated design production capability with tighten tolerance, precise dimensions

4. Low thermal conductivity, less than 3 W/m.k at room temperature, so it can couple with metal well

5. Exceptional high hardness, over than 1300 MPa for Vicker hardness, it leads to high wear resistance

6. Can withstand higher temperatures up to 2400° under vacuum or reduced atmospheres

7. Exceptional fracture toughness than almost advance ceramics, reaches up to 8 Mpa m1/2

8. Chemical inertness which can withstand most of acids and alkali, aging resistance and not rust forever 

9. Resistance to molten metals and avoid any metal residual on surface due to an extraordinary melting point

Description of zironia ceramic tube

Most of the stabilized zirconia used in industrial refractories are prepared by electrofusion. In the zircon fusion process, carbon and stabilizer calcium oxide are added. While silicon is removed, the zirconia and calcium oxide react to form a solid solution, which is then crushed and sized to obtain stable zirconia. The stable and partially stabilized zirconia used in fine ceramics is generally prepared by wet methods. The neutralization precipitation method is currently mature and commonly used. Dissolve the purified zirconium oxychloride in pure water, filter to remove insolubles, adjust the zirconium concentration in the solution, and add the required amount of yttrium chloride solution (or chloride solution of other rare earth metals or alkaline earth metals), then add ammonia Neutralize precipitation. After washing the precipitate with hot water, it is filtered, dried and calcined. The calcined product can be crushed to obtain ultra-fine stable zirconia powder.
Partially stabilized zirconia is prepared by controlling the amount of stabilizer added to make it insufficient to achieve complete stability. Partially stabilized zirconia has high strength and thermal shock resistance, and has a wide range of uses in Structural Ceramics.
