Cubic closed packing (CCP) is an alternative name given to face centred cubic (FCC). They both have the closest possible packing of atoms. However, the layers of plane sheets of atoms are arranged in a slightly different manner. Therefore, the total number of atoms in a unit cell = 4 ...
In a close packing arrangement, the interstitial void formed by the combination of two triangular voids of the first and second layer is called octahedral coid. Thus, double triangular void is surrounded by six spheres. The centre of these spheres on joining, forms octahedron. If R is the rad...

The cubic closed packing is CCP, FCC is cubic structures entered for face. When we put the atoms in the octahedral void, the packing is of the form of ABCABC, so it is known as CCP, while the unit cell is FCC. What is the value of Z in BCC? In numericals,we use Z values-1...
2.2 CLOSED PACKED STRUCTURES OF METALS The main structure observed in metal deposits is a closed packing of identical spheres. A two-dimensional arrangement is shown in Figure 2.1. A layer of spheres is placed in the depression of the first layer to extend this arrangement into the third dimens...
The reactor can be divided into Reactor with open flat cover, Reactor with open butt welded flange and closed Reactor. Each kind has its own wide application range and merits. Reactor consists of components such as body, cover, jacket, agitator, driving devic...
The 19-atom closed shell structures (“magic number” clusters) are known in the literature to be the building blocks for the homoepitaxial Cu growth on Cu(111).28 Sometimes, the clusters contain a few more atoms or come in contact with each other forming aggregates that separate again ...
The packing container has a rectangular prismatic body, closed at top and bottom by base and cover sections folded over from the sidewalls. The cover sections (6-9) have engaging portions (6', 7', 8', 9', 14) at their edges towards each other. These fit part of the way into each...
