Porous Alumina Plates

Advantages of Porous Alumina Plate

1. Alumina ceramic plate has a relatively high thermal conductivity. Compared with traditional circuit board materials, it can dissipate the heat generated during the operation of the circuit more effectively.

2. Alumina ceramic plate can maintain stable performance at relatively high temperatures.

3. Alumina ceramic plate is an excellent insulator, which can effectively prevent short circuits and leakage current phenomena between circuits.

4. The relative dielectric constant of alumina ceramic plate is relatively low, which can reduce the delay and distortion of signals during the transmission process.

Applications of Porous Alumina Plate

1. Alumina ceramic plates are widely used in gas and liquid filtration.

2. Alumina ceramic plate is an excellent substrate for catalysts in chemical reactions.

3. Alumina ceramic plates are commonly used as insulation materials for furnaces and kilns.

4. Alumina ceramic plate is suitable for biological filtration and tissue engineering scaffolds.

5. Alumina ceramic plates are used as substrates and separators in fuel cells and batteries.

Factory Equipment

Alumina

Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
