Description
High temperature resistance Alumina Ceramic Tube
Features Of Alumina Ceramic Tube:
- Extreme high temperature stability under reducing, inert and high vacuum condition under high temperature up to 1800C.
- Extreme wear and abrasion resistance.
- Chemical corrosion resistance under high temperature.

Properties of Alumina Ceramic:
- Very good electrical insulation (1×1014to 1×1015 Ωcm)
- Moderate to extremely high mechanical strength (300 to 630 MPa)
- Very high compressive strength (2,000 to 4,000 MPa)
- High hardness (15 to 19 GPa)
Alumina ceramic, also known as aluminum oxide (Al2O3), is a versatile and high-performance ceramic material that has gained significant attention in various industries due to its exceptional mechanical, thermal, and electrical properties.Welcome to contact us.
Moreover, alumina ceramic is used in the chemical processing industry for manufacturing components such as valves, pumps, and liners for pipelines, where its resistance to chemical corrosion and wear are essential.
