- Excellent crystal phase stability, high hardness, good dimensional stability, suitable for the needs of precision scientific research scenarios.
Application Fields
- Transparent ceramics, high-pressure sodium lamp tubes, EP-ROM windows;
- Preparation of single crystals (ruby, sapphire, etc.) and yttrium aluminum garnet;
- Scientific research consumables such as high-strength alumina ceramics, C substrates, packaging materials, and high-purity crucibles;
- Precision polishing materials (suitable for semiconductor, metal products and other fields);
- Research substrates such as catalysts/catalyst carriers, fluorescent materials, and composite materials;
- Scientific research and development related to aerospace materials (such as aircraft wing leading edges).
Packaging and Storage
Packaged with inert gas anti-static packaging, it should be stored in a sealed, dry and cool environment; avoid long-term exposure to air to prevent moisture absorption and agglomeration, which may affect dispersibility and use effect.
