Specification of Alumina Al2O3 Ceramic Thin Plate Alumina Ceramic Substrate

This alumina ceramic plate, referred to as Al2O3 ceramic substratum, gives strong performance. Its main material is aluminum oxide. You get high purity degrees, generally 95% or 99%. This purity matters for constant outcomes. Typical plate dimensions are slim, like 0.25 mm, 0.5 mm, or 1.0 mm. Density issues for your application. Criterion sizes consist of 100x100mm or 50x50mm. Custom dimensions are possible as well. The surface area finish is very smooth. This smoothness is critical for electronics. Surface area roughness is usually much less than 0.4 microns Ra. Precision machining achieves this. Sprucing up makes it even smoother if required.

This product deals with heats well. Its maximum usage temperature level is around 1600 ° C. It resists warmth shock effectively. So it works dependably in hot settings. The thermal development coefficient is reduced, about 7.0 x 10 ^ -6/ ° C. This security stops fracturing under warmth adjustments. It’s a strong electrical insulator. Dielectric toughness is high, surpassing 10 kV/mm. This protects against electric failure. Quantity resistivity is additionally very high at area temperature level. This makes certain good insulation. Its dielectric constant is moderate, normally around 9-10. This suits several electronic usages.

Mechanical toughness is another key point. Alumina is really hard and put on immune. Vickers firmness is roughly 15 GPa. It endures abrasion successfully. Flexural toughness is great, often over 300 MPa. This suggests it does not damage conveniently under bending pressure. Density is high, near 3.8 g/cm FIVE. This makes it strong and durable. Chemical resistance is excellent. It handles strong acids and bases well. This stability is necessary for extreme problems. It does not respond quickly with various other materials.

You discover these plates in numerous requiring locations. They are necessary for thick film and slim movie circuits. Electronics rely on them for substrates. They work well in sensing units and heating units. LED plans typically utilize them. High-power components require their insulation. They serve in laser components too. Semiconductor tools uses them often. Heating system components gain from their warmth resistance. Insulators in high-voltage systems depend upon them. Wear parts utilize their solidity.
