Product Introduction

Product Introduction:

4N high purity nano alumina powder,CAS#: 1344-28-1, has stable crystal phase, high hardness and good dimensional stability, especially to improve the compactness, smoothness, thermal fatigue, fracture toughness, creep resistance and wear resistance of polymer products of ceramics Especially notable. Since nano-alumina is also a far-infrared emitting material with excellent performance, it is used in chemical fiber products and high-pressure sodium lamps as far-infrared emitting and thermal insulation materials. In addition, a-phase alumina has high resistivity and good insulating properties, and can be used in the main parts of YGA laser crystals and integrated circuit substrates.
