1800C Alumina Ceramic Tube
My factory looking for distributors.
Advantages of 1800C Alumina Ceramic Tube
Alumina ceramic tubes, with their advantages in wear resistance, corrosion resistance, high temperature resistance, mechanical strength, heat insulation, and good cost-performance ratio, play an irreplaceable role in many links of the mining industry such as material transportation and ore processing. Alumina ceramic tubes provide strong support for the efficient, stable, and sustainable development of the mining industry.
Application of 1800C Alumina Ceramic Tube
1. As a conveying pipeline or protective casing for high-temperature furnaces, it protects thermocouples in high-temperature measurements.
2. As an insulating tube in high-voltage switches or vacuum circuit breakers to prevent current breakdown.
3. As an electrolyte or connector material, it supports high-temperature electrochemical reactions.
4. Maintain structural stability in a vacuum environment and avoid outgassing contamination.
