Producing Iron-Rich Spheres at 1500°C

[Andre-]

Hi. I am having trouble finding sources to the information that i am seeking (sometimes you find really good phyisics/chemistry books through google).

Nm particles of iron 100 nm has the same melting point as iron in bulk. Is there any chemistry books online that shows why even small particles of iron must be heated up to 1500C in order to produce iron-rich spheres?. iron-rich spheres can only be produced by a very high temperature of 1500C even if the particles are very small, as i understand it. As i understand it, it is impossible to get iron-rich spheres from just heating metals with low temperatures of 500C...

So what i am looking for is some good sources or websites that explains all this, i am offcourse interested in hearing your comments also.

Thanks for the help in advance.

To find sources for the information you are seeking, try searching through academic databases such as Google Scholar, JSTOR, and ScienceDirect. These databases often have articles written by experts in the field that will have the information you are looking for. You may also want to look into books on physics and chemistry that discuss the properties of metals and their melting points. Finally, you could consult with a professor or other expert in the field to get more detailed information.

Hello, there are several factors to consider when producing iron-rich spheres at high temperatures. First, it is important to understand that the melting point of a material is not solely dependent on its size, but also on its composition and structure. For example, iron nanoparticles may have a lower melting point than bulk iron due to their high surface area and different crystal structure.

However, when producing iron-rich spheres, the goal is to create a uniform composition and structure throughout the entire sphere. This requires a high temperature of 1500°C to fully melt the iron and allow it to form into a spherical shape. At lower temperatures, there may not be enough energy to fully melt the iron and create a homogeneous structure, resulting in a mixture of different compositions and shapes.

As for sources, you can find more information on the properties of nanoparticles and their melting points in scientific journals and textbooks, such as "Nanomaterials: An Introduction to Synthesis, Properties, and Applications" by Dieter Vollath. Additionally, there are many online resources available through university websites and databases that can provide further insights into this topic. I hope this helps.
