Product Description

nano magnetite (Fe3O4) with particle size *5 nm ,purity *9.8%,red powder are used for many applications such as waste water treatment and electronics chemicals

Nanoparticles are microscopic particles with a diameter range between 1 and **0 nm. These particles possess physical properties such as conductance, uniformity, or special optical properties, which make them ideal for use in biology and materials science, and they have become an area of intense scientific research due to the broad range of potential applications in the optical, biomedical, and electronic fields.

Nanoparticles can be in the form of nanocrystals, nanopowders, or nanoclusters, and the particles act as a bridge between bulk materials and atomic or molecular structures. They exhibit a number of special properties corresponding to the bulk material.

For instance, the bending of bulk copper happens with the movement of copper atoms/clusters at the *0 nm scale. Copper nanoparticles that measure less than *0 nm are known as super-hard materials, which do not display the same ductility and malleability as bulk copper.

There are different types of nanomaterials such as carbon nanotubes, fullerenes and buckyballs, dendrimers, fine and ultrafine particulates in the air, titanium dioxide nanoparticles, quantum dots and nanocrystals, silver nanowire, silver nanoparticles, and other nano-sized particles.

The properties of materials alter as their size reaches the nanoscale and as the percentage of atoms at the materials surface becomes significant. However, the change in properties is not always desirable.

Ferroelectric materials that measure less than *0 nm can change their magnetization direction using room temperature thermal energy, making them ineffective for memory storage.

Nanoparticles frequently have unpredicted visible properties as they are small enough to lock up their electrons and generate quantum effects. For instance, gold nanoparticles look deep red to black in solution.

Nanoparticles have a very high surface area to volume ratio, which provides a great driving force for diffusion, particularly at high temperatures. Sintering can be performed at lower temperatures across shorter time scales compared to larger particles, and the large surface area to volume ratio decreases the initial melting temperature of nanoparticles.
