Nano aluminium powder NMD Metalpowders’ product is metallic aluminium (Al) with particles in the nanometre range. It is one of the Nano-metal powders and is of interest for materials development and specialised industrial applications where surface reactivity and fine distribution within the material system are required.
The nanoscale particles have a large surface area in relation to their volume. As a result, surface properties, the oxide layer and chemical composition have a significant influence on the reactivity and processing of the powder.
Properties and advantages
- Large specific surface area: The fine particles provide a large surface area for interactions with other components of the material.
- High reactivity: Of interest for specialised chemical and pyrotechnic applications; the reaction behaviour depends, amongst other things, on the surface condition.
- Potential for composite materials: Aluminium nanoparticles are being investigated with a view to specifically influencing their thermal and mechanical properties.
- Adaptation to material systems: Appropriate surface treatment and dispersion can facilitate incorporation into a matrix.
Aluminium forms an oxide layer on its surface. In the case of nanoparticles, therefore, the proportion of metallic aluminium is relevant in addition to the total aluminium content. Additional passivation may affect behaviour during storage and processing.
Areas of application
Pyrotechnic applications
Due to its reactivity, nano-aluminium powder is used in industrial pyrotechnics and in the development of specialised reactive materials. The choice of powder grade depends on the intended application, the particle size distribution and the surface condition. The information provided in the safety data sheet for the specific product supplied is decisive for its handling.
Composite materials and thermal management
In materials research, aluminium nanoparticles are being investigated as fillers for composite materials, for example for heat management in the Semiconductors and electronics. The aim is to improve heat transfer within the material.
The thermal conductivity that can be achieved depends on the particle content, surface treatment, distribution and bonding to the surrounding matrix. Mechanical properties such as strength and hardness are also determined by the material system as a whole.
Research into energy storage systems
Aluminium nanoparticles are being investigated as a component of novel electrode materials, for example in combination with carbon-based structures. The research focuses on thermal conductivity and electrochemical behaviour. Improvements in capacity or service life must be demonstrated for the respective electrode system.
Technical Specifications and Choice of Materials
When selecting nano-aluminium powder, the size of the individual primary particles, any particle agglomeration and the chemical composition are key factors. We will agree specific particle sizes, purity levels and supply forms with you on request.
- Particle size: Desired primary particle size and requirements for particle size distribution.
- Composition: Total aluminium content, metallic aluminium content and relevant associated elements.
- Surface condition: Requirements regarding oxide layers, passivation or other surface treatments.
- Processing: Intended process, dispersibility requirements and desired dosage form.
