Alumina Ceramic Components


Alumina Ceramic

Alumina ceramic, also known as alumina or aluminum oxide (Al2O3), is an industrial oxide ceramic known for its extreme hardness and high thermal conductivity. The properties of alumina ceramics make them one of the most widely used ceramics for structural, wear, and corrosive environments. Alumina ceramics are typically manufactured from bauxite and can be shaped using injection molding, die pressing, isostatic pressing, slip casting, diamond machining, and extrusion. Like aluminum nitride and other important engineering materials, alumina can be produced by dry press and sinter or by hot pressing using appropriate sintering aids. Alumina-based ceramics are one of the most studied and characterized advanced ceramic materials known today.

Advantages of Alumina Ceramic Components

Alumina ceramic components have excellent hardness (Mohs 9), which is particularly beneficial in applications that require durability and minimal material degradation. With high melting point and extreme temperature resistance (up to 1800 ℃), the high resistivity of alumina ceramic components makes them excellent insulators (KV/mm 20), resistant to most acids and alkalis, making them suitable for corrosive environments.

Applications of Alumina Ceramic Components

1.Alumina ceramic components are used to manufacture electronic substrates and components that require high resistance.

2. It is also used for pumps and valves in the chemical industry.

3. Can be used for medical implants, prosthetic devices, and dental applications.

4. Alumina ceramic components are used for sensors, spark plugs, and various engine components.

Our factory

Alumina Ceramic Components

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.

Isostatic pressing: During the isostatic pressing procedure, binders are blended with the ceramic powder. As a result of this process, the powder transforms into freely flowing granules that can effortlessly fill the molds.

Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
