1. Easy to press - form: The granulated particles have good sphericity and high fluidity. Coupled with a specific particle - size distribution, during the pressing process, the particles can fill and bond well with each other. Whether in the dry - pressing or isostatic - pressing forming process, it exhibits excellent fluidity and plasticity and can be easily pressed into blanks of various specifications.

2. High flexural strength: Benefiting from its high - purity alumina composition and special production process, the crystal structure inside the material is more compact and uniform. When subjected to external forces, this structure can effectively disperse stress, enabling ceramic products to have better bending resistance during use, being less prone to cracking or deformation, and providing a strong guarantee for long - term stable use.

3. Low sintering temperature: The primary crystal particles are small and have high sintering activity. This enables the product to complete sintering at 1600 °C. This feature not only reduces energy consumption but also lowers the high - temperature resistance requirements for production equipment, extending the service life of the equipment.

4. Good surface polishing effect: The microstructure is uniform, and the surface effect is highly consistent. The uniform microstructure and low impurity content ensure that there are no local hardness differences or defects during polishing, thus enabling a mirror - like polishing effect. This excellent surface quality plays a crucial role in application fields with high requirements for surface precision, such as optics and electronics.

5. Uniform microstructure: The product's microstructure shows a high degree of uniformity. When observed at the micro level, the alumina grains are evenly distributed, the grain boundaries are clear, and there are no obvious defects or impurity - enrichment phenomena. This uniform microstructure is the basis for its excellent properties. It ensures the stability and consistency of the material's physical, chemical, and mechanical properties, enabling ceramic products to exhibit reliable performance in different usage environments.
