    99% High Alumina Ceramic Tubes For Furnace Thermocouple Protection

     

    Features:

    1. High hardness.

    2. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is

    widely used in areas where resistance to high temperatures is essential.

    3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.

    4. High electrical resistivity : Alumina is an electrically insulating material.

    5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and

    alkaline solutions.

    6 Good chemical stability of alumina leads to high corrosion resistance.
