Product Description

Calcined alumina powder plays a key role in many high-tech fields due to its high purity, high hardness, and excellent thermal stability. Its main application areas include:
1. Electronic Manufacturing and Semiconductors: Used for electronic ceramic substrates, such as integrated circuit boards, sensors, capacitors, and vacuum components, to meet high-frequency insulation and high reliability requirements.
2. Ceramic industry: manufacturing insulators, mechanical components (such as bearings and seals), and sanitary ware to improve wear resistance and insulation performance.
3. Refractory materials: made into refractory bricks, crucibles, and castables, suitable for high-temperature industrial environments (with a temperature resistance of up to 2050 ºC).
4. Thermal conductive material: high-purity spherical powder is used as a thermal conductive filler for silicone pads, potting adhesives, and engineering plastics to optimize heat dissipation efficiency.
5. Thermal conductive material: High purity powder is used for thermal conductive fillers such as thermal conductive adhesive and silicone grease to optimize heat dissipation performance.
6. In the field of new energy, it is particularly used for coating lithium battery separators, supporting the improvement of battery performance.
7. Abrasive and wear-resistant components: used in the manufacturing of bearings, seals, and cutting tools to extend equipment life.
