Aluminium Oxide Ceramic Plate
My factory looking for distributors.
Advantages of Aluminium Oxide Ceramic Plate
Aluminium oxide ceramic plates are mainly made from AL2O3 as raw material and calcined at 1700 ℃. Aluminum oxide ceramic plate has good hardness (Hardness Mohs 9) and corrosion resistance, Density（3.88 g/cm3）Water absorption（0.01%），Flexural strength（350 Mpa）， Customizable shape and thickness.
Applications of Aluminium Oxide Ceramic Plate
1. Aluminium oxide ceramic plate is often used in chemical and physical grinding environment, especially high purity alumina is a very good material for producing wear-resistant components.
2. Aluminium oxide ceramic plate are mainly used in chemical and physical conditions and are good corrosive media.
3. Aluminium oxide ceramic plate can be used to manufacture circulating pumps, reciprocating pumps and resonator-supported products.
4. Aluminium oxide ceramic plate is often used in water resources management, medical treatment, automobiles, telecommunications and household appliances applications.
Quality testing standards
1. Visual inspection of the substrate for any signs of damage or irregularities.
2. Measurement of the length, width, and thickness of the substrate to check for accuracy.
3. Checking for any pinhole defects in the substrate.
4. Verification of the material and chemical composition of the substrate.
