High temperature resistant alumina ceramic rod

High temperature resistant alumina ceramic rod is a ceramic material mainly composed of alumina (Al ₂ O3), with an alumina content usually above 95%.
High melting point: The melting point of alumina is as high as 2050 ℃, allowing it to remain stable at extremely high temperatures.
High temperature resistance: It can be used for a long time in high temperature environments above 1600 ℃, and some special products can even withstand temperatures above 1700 ℃.
Low thermal expansion coefficient: Excellent dimensional stability at high temperatures, avoiding deformation or cracking caused by thermal expansion and contraction.
High hardness and strength: It has extremely high mechanical strength and wear resistance, suitable for withstanding high loads and wear environments.
Corrosion resistance: It has good corrosion resistance to acids, alkalis, and various chemical media.
Electrical insulation: It exhibits excellent electrical insulation performance at both high and room temperatures.
