4N high-purity nano alumina

Basic Information:

1. Product Model: HN-L30

2. Properties: Nano-alumina (α-phase) has high hardness and excellent dimensional stability, making it widely applicable for reinforcement and toughening in various products such as plastics, coatings, rubber, ceramics, and refractory materials. It is particularly effective in enhancing thermal conductivity in plastics and rubber, as well as improving the density, surface finish, thermal shock resistance, fracture toughness, creep resistance of ceramics, and the wear resistance of polymer materials. Additionally, due to its outstanding performance as a far-infrared emission material, nano-alumina is used as a far-infrared emitting and thermal insulation material in chemical fiber products and high-pressure sodium lamps. Furthermore, α-phase alumina has high electrical resistivity and excellent insulating properties, making it suitable for use in key components of YAG laser crystals and integrated circuit substrates.
