High Purity Alumina (HPA) possesses superior physical and chemical properties, such as a high melting point, good thermal stability, high hardness, high mechanical strength, excellent electrical insulation, and corrosion resistance. These properties make it widely used in numerous high-tech and high-end industrial sectors.

Its main application areas include:

Electronics and Information Technology:

• LED Chip Manufacturing: HPA is the crucial raw material for producing Sapphire Substrates. These substrates are used to manufacture LED epitaxial chips and are a major driving force behind the rapid development of the LED industry.

• Semiconductor Manufacturing: Used to produce various advanced ceramic materials and sputtering targets, which are vital for the performance of semiconductor devices.

Advanced Ceramics and Structural Materials:

• Used to prepare high-performance ceramic components, such as refractory materials, abrasives, cutting tools, bearings, and various precision ceramic parts.

New Energy and Battery Technology:

• In lithium-ion batteries, HPA is used as a coating material to improve the thermal stability and safety of the battery separator, thereby enhancing the battery's cycle performance.

Other Specialized Fields:

• Catalyst carriers, biomedical materials, and other materials requiring high hardness, high purity, and excellent thermal/electrical properties.

In summary, High Purity Alumina is an essential foundational raw material supporting the development of high-tech industries, especially in electronics (LEDs and semiconductors), new energy, and advanced manufacturing.
