Aluminum Metal and It's Properties                                            Aluminum  is a silvery-white chemical element with symbol Al and atomic number 13. It's a soft, nonmagnetic and ductile metal. By mass, aluminum makes up about 8% of the Earth's crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust.  Aluminum  metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. Aluminum  is remarkable for its low density and its ability to resist. Aluminum and its alloys are vital to the aerospace industry and important in transportation and building industries, such as building facades and window frames. The oxides and sulfates are the most useful compounds of  aluminum . Proper...

- Melting point of Aluminum Nanoparticles is 660.32 °C. - Boling point of Aluminum Nanoparticles is 2519 °C.7 - The morphology of Aluminum Nanoparticles is spherical and they appear as black or grey-black powder. - Aluminum nanoparticles are highly reactive, because of that measures should also be taken to protect aluminum nanoparticles from moisture, heat, and sunlight. - Aluminum nanoparticles are highly effective catalysts. - When Aluminum nanoparticles added into solid rocket fuel, it helps improve combustion speed and considerably increases combustion heat and combustion stability. The burning rate of solid propellant can be 5-20 times higher using aluminum nanopowders compared to powders with larger particle sizes. - Adding about 5-10% of aluminum nanoparticles into standart aluminum powder improves the sintering processes of ceramics, with high heat-transfer performance, increased density, and improved the thermal conductivity o...
