At 600°C, the situation was almost the same as at 550°C except that a weak Al diffusion was observed in some spots (arrows on Fig. 2) as shown by EDS, likely corresponding to grain boundaries of the nickel substrate.
This could imply that in these conditions diffusion does not markedly depend on the number of contact points between spherical Al particles and nickel substrate.

Despite the performance of the different crystal structure MnO2 is big difference, its properties are also strongly dependent on the grain size and morphology, particularly the nanostructure.
It can be seen that the layer folded δ-MnO2 microspheres contained a great number of water molecules, while the water content in α-MnO2 was far lower than that in δ-MnO2 sample, which further indicated that the crystal structure of MnO2 had a close relation with bound water. δ-MnO2 contained more bound water and inter-layer K+ due to its large layer interval; in contrast, the amount of bound water in α-MnO2 in tunnel structure was much lower than that in δ-MnO2.

Near infrared spectrum wavelength range from 760nm to 2500nm, the count number of the point is over 30point according to standard GBT17683.1-1999 .
But if the heat treatment temperaturewas higher 700 ℃, the grain size of products increased, and near infrared reflection performance decreased.
