The global storage capacity of alumina oxide is the one second to silicon oxidation only; it is a component of raw ceramic material. In alumina oxide molecule, aluminum atoms hold strong chemical bonds to oxygen atoms, which form extremely high hardness among its oxides. And the stable chemical properties make the alumina oxide in high corrosion resistance to most acids, alkalis and chemicals as well as melted solutions. The structural strength of Al2O3 is influenced by its density and microstructure; in normal temperature condition, it holds the highest strength; when the ambient temperature rises up to 1000˚C, the material structure decays apparently. Also, the Al2O3 holds relatively lower thermo-expansion coefficient.
The properties (thermal, mechanical, physic & chemical one, etc.) of Al2O3 are all relevant to its purity contained in the base organization.
Generally speak, the higher alumina oxide purity the material holds, the better thermal conductivity it behaves; when an extremely high alumina oxide purity reaches, the material¡¦s specific density will approach its theoretic one and earns excellent mechanical properties in response.
Nowadays, vendors have massively applied alumina oxide to replace metallic parts in the prospective of improving the properties of anti-corrosion, anti-wear, thermo-endurable capability and strength-enhancement. For now, not only the high-tech semiconductor vendors massively apply alumina oxide-based ceramic devices, other industries also gradually use this ceramic material to improve product properties, elevate efficiency and reduce cost.
