Compreensão simples da safira industrial
Key Takeaways Industrial sapphire is corundum (Al2O3) — natural or synthetic — that does not reach decorative gem grade and is instead used for its hardness, temperature resistance and insulation. It serves two main purposes: substrate materials such as LED semiconductor substrates, and window materials for watch dials, aerospace and precision manufacturing. Its value comes from corundum's property set: high temperature and corrosion resistance, Alta resistência, Mohs 9 dureza, resistência ao desgaste, electrical insulation and hermeticity. The processing chain runs seed crystal, growth, orientação, boule,...
