Nano-coating materials are new functional materials formed by chemical combination and chemical adsorption of nano-alumina, nano-zirconia, nano-titanium oxide and other nano-powders, and have the characteristics of inner nanoparticles. The ratio of the surface atomic number to the total atomic number of nano-alumina zirconium titanium nanoparticles increases significantly as the particle size decreases, and the surface energy and surface tension of the particles also increase, causing changes in particle properties. The crystal field environment and binding energy of the surface atoms of the particles are different from those of the internal atoms. There are many dangling bonds and are unsaturated. Therefore, they are easily combined with other atoms and become stable. Therefore, they have a high chemical activity.
Let’s do two simple calculations to understand the change in surface area.
Particles are calculated as spheres, and the surface area is the volume
①The relationship between the surface area of one particle and the two is processed
First find out how many particles (units) the particle can process
[() /][/]
Below, find the surface area of a particle as a multiple of the area of the particle (unit)
[][()] times
②The surface area of one gram of particles (titanium Density)
First find out how many particles (units) can be processed by one gram of nano-alumina
The volume unit of one gram of nano-alumina is ㎝㎝

The surface area of one gram of nano-alumina is (unit)
[(/)][]㎡
And the surface area of one particle of nano-alumina is only ㎡
