The impregnation of the nickel promoted an increasing in the size of the particles, this carried to reduction of the superficial area of the same, of the volume and of the diameter of the pores of the structure of the material.
The proportion of each reagent in the mixture obeyed the concepts of the chemistry of propellants and was calculated according to the valencies of the metallics elements [3].
Studies about catalytics nanoparticles supported by ceramics materials show that the Ni/α-Al2O3 catalysts modifieds with metallics oxides, such as Fe2O3, SiO2 and CeO2, operating in similar conditions to Ni/α-Al2O3 catalysts not modified, are less prone to the structures of carbon formation, i. e., they are more resistant to the coke formation and consequently presented superior catalytic activities [8].

The influence of Al2O3 incorporated in porous solid polymer on the structure and properties have been examined.
The pores have got bigger and the membrane structure has gradually become incomplete when the amount of acetone added.
Then, plenty of electrolyte storage space can be formed by this porous structure; moreover, this special structure can provide a channel for lithium ion, reduce the lithium ion migration resistance and improve the ionic conductivity of polymer membrane.
This reactor changes the structure of the polymer chain and prevents reforming of the chain segment.

Different ceramics have been produced by high-energy milling, which present homogeneous composition and structure [6-9].
Initially, both the values were increased after milling for 40 min and subsequently reduced in the a-Al2O3 and TiO2 crystalline structures of powders milled for 60 min.
For longer milling times, only the cell volume of TiO2 was increased in 3Al2O3-TiO2 powders, indicating that Al atoms were dissolved into the TiO2 lattice to form a metastable structure.
However, the formation of porous structures can contribute for growing and anchoring of bone tissues.
