SINTYRON Customized High Strength Yttria-stabilized zirconia ceramic tube

Zirconia ceramic tubes are advanced industrial components made primarily from zirconium dioxide (ZrO₂). Through a process called stabilization (often with yttrium oxide, Y₂O₃), they achieve exceptional mechanical and thermal properties that make them indispensable in high-performance and demanding applications where common materials like metals or other ceramics (e.g., alumina) would fail.

SINTYRON Customized High Strength Yttria-stabilized zirconia ceramic tube

Zirconia ceramic tubes (ZrO₂ ceramic tubes) are high-performance ceramic products, mainly composed of zirconia. They possess excellent characteristics such as high temperature resistance, corrosion resistance, high strength and wear resistance.

Mechanical Properties: Compressive strength reaches 1200-1400 MPa, fracture toughness is four times that of alumina ceramics, wear resistance is excellent, and the surface finish is near-mirror-like.

Thermal Properties: High-temperature resistance (can operate stably above 1600°C), with a thermal expansion coefficient close to that of metal (9.4×10⁻⁶/°C at 25-1500°C), preventing deformation caused by thermal expansion and contraction.

Electrical Properties: Low thermal conductivity (2.09 W/(m·K) at 1000°C), suitable for use as a solid electrolyte membrane in high-temperature fuel cells.

Chemical Stability: Resistant to corrosion from strong acids, alkalis, and organic solvents, extending service life in chemical pipelines by more than three times.

Application fields
1.Industrial High-Temperature Furnaces and Sensors:
Thermocouple Protection Tubes: This is one of the most classic applications. It protects the internal temperature sensing element (thermocouple wire), enabling long-term stable operation in harsh environments such as high temperatures, corrosive atmospheres (such as reducing atmospheres), and molten metal.
Furnace Tubes: Serves as the hearth of small high-temperature experimental furnaces, providing a clean, high-temperature environment.
2.Mechanical and Wear-Resistant Components:
Wear-Resistant Liners and Guide Sleeves: Used as inner linings in equipment conveying powders, granules, or fibers, they significantly extend equipment life.
Bearings and Bushings: Ceramic bearings offer advantages over metal bearings, particularly in lubricated, high-temperature, or corrosive environments.
3.Medical: Primarily used in dentistry as furnace tubes for dental sintering furnaces, zirconia furnace tubes provide an extremely stable and clean high-temperature environment, ensuring the sintering quality of dental restorations (such as zirconia crowns and bridges) without causing contamination.
4.Energy, Electronics, and Aerospace:
A key component of solid oxide fuel cells (SOFCs).
Insulating sleeves and structural components in certain special applications.
