Alumina Ceramic Custom Components High Hardness for Semiconductor Manufacturing Equipment

Alumina Ceramic Custom Components High Hardness for Semiconductor Manufacturing Equipment

Alumina ceramic custom components are advanced ceramic parts manufactured through a series of processes including powder preparation, forming, high-temperature sintering, and precision machining, using high-purity aluminum oxide (Al₂O₃) as the primary raw material. The alumina content typically ranges from 75% to 99.9%, with higher content yielding superior performance. These products are not standard off-the-shelf items but rather functional, engineered core components designed and produced according to customers' specific application scenarios and technical requirements.

Alumina ceramic custom components Key Parameter

Alumina ceramic custom components Key Characteristics

The exceptional properties of alumina ceramic make it stand out among numerous engineering materials:

① Extreme Hardness and Wear Resistance:

• With a Mohs hardness of up to 9, second only to diamond and silicon carbide, it is highly resistant to scratching and wear. Even under harsh conditions with particulates or frequent friction, it maintains dimensional stability and surface smoothness over long periods, significantly extending equipment service life.

② Excellent Electrical Insulation:

• It maintains high resistivity even in high-temperature and high-humidity environments, making it an ideal high-temperature insulating material. Widely used in circuit substrates, insulating rings, coil bobbins, etc., it ensures the safe and stable operation of electronic equipment under high voltage.

③ Good Chemical Stability:

• It exhibits strong resistance to most acids, alkalis, and solvents, is insoluble in water, oxidation-resistant, and不易腐蚀 (not easily corroded). This makes it highly suitable for chemical, biomedical, and semiconductor equipment, serving as chambers, pipes, or components that come into contact with corrosive media.

④ High Heat Resistance and Low Thermal Expansion Coefficient:

• With a melting point as high as 2050°C, it can operate long-term in high-temperature environments up to 1600°C. Its low thermal expansion coefficient means minimal deformation under rapid temperature changes, good thermal shock resistance, and no cracking due to thermal cycling.

⑤ High Mechanical Strength:

• Although less tough than metals, it has very high compressive strength and can withstand significant loads.
