Description

Zirconia Ceramic Protection Tube

Zirconia Ceramic Protection Tube exhibits excellent thermal conductivity and thermal shock resistance, making it well-suited for applications requiring efficient heat dissipation and resistance to thermal stress.

Properties:

1.Excellent thermal insulation/low thermal conductivity (2.5 to 3 W/mK)
2.Very high resistance to crack propagation, high fracture toughness (6.5 to 8 MPam1/2).

Zirconia (ZrO2)ceramic is an extremely refractory material. It possesses excellent chemical inertness and corrosion resistance at temperatures well above the melting point of alumina.

Applications of Zirconia Ceramic:

In the aerospace industry, zirconia ceramic is utilized in the manufacturing of parts and components for aircraft engines, avionics, and satellite communications systems. Its ability to withstand high temperatures and harsh environmental conditions makes it a valuable material for these critical applications.
