Solid solution homogeneous

Solid solution Homogeneous solid phase with variable composition, e.g., Cui cAu c, also called mixed crystal. In general boundary phases have isotypical crystal structures, similar atomic radii, electronegativity, and valence electron concentration.

System in which the two components form a continuous series of solid solutions. In all the preceding examples the individual components (A or B or A By) form separate crystals when solidifying from the melt. There are, however, a number of examples of the separation of a homogeneous solid solution of A and B (or A and A By, etc.). 

When a pure metal A is alloyed with a small amount of element B, the result is ideally a homogeneous random mixture of the two atomic species A and B, which is known as a solid solution of in 4. The solute B atoms may take up either interstitial or substitutional positions with respect to the solvent atoms A, as illustrated in Figs. 20.37a and b, respectively. Interstitial solid solutions are only formed with solute atoms that are much smaller than the solvent atoms, as is obvious from Fig. 20.37a for the purpose of this section only three interstitial solid solutions are of importance, i.e. Fc-C, Fe-N and Fe-H. On the other hand, the solid solutions formed between two metals, as for example in Cu-Ag and Cu-Ni alloys, are always substitutional (Fig. 20.376). Occasionally, substitutional solid solutions are formed in which the... 

Let us consider a mass m of solid solute, and a mass M of solvent, brought together in a calorimeter. When the whole has passed into a homogeneous solution at the original temperature, a quantity of heat Q will have been absorbed. We now set, by wTay of definition ... 

In certain cases, however, the solid which separates is a homogeneous mixture of both components, and hence may be referred to as a solid solution. These are often called mixed crystals, but the name is clearly unsuitable in view of the... 

The relations apply also to the case of a liquid mixture of two substances which is solidifying to a homogeneous solid which contains the two substances in proportions depending on the composition of the melt—a so-called solid solution or mixed crystal ( 138). 

The entropy of a condensed homogeneous solution (isomorphous solid solution) is then ... 

Example butter, an emulsion of water in butterfat. solid solution A solid homogeneous mixture of two or more substances. 

Isomorphism. TiC is isomorphous with TiN and TiO. Thus oxygen and nitrogen as impurities, or as deliberate addition, can substitute for carbon to form binary and ternary solid solutions over a wide range of homogeneity. These solutions may be considered as Ti(C,N,0) mixed crystals. TiC forms solid solutions with the other monocarbides of Group IV and V. It is the host lattice for WC.li" ... 

VsGcsB is the end member of a homogeneous solid solution V5Ge3Bx (0 < x 1, 700°C) starting from binary V5Ge3-... 

A solution is a homogeneous mixture of two or more substances. As described in Chapter 3, a solution contains a solvent and one or more solutes. The solvent determines the state of the solution, and normally the solvent is the component present in the greatest quantity. The most common solutions are liquids with water as solvent, but solutions exist in all three states of matter. The atmosphere of our planet, air, is a gaseous solution with molecular nitrogen as the solvent. Steel is a solid solution containing solutes such as chromium and carbon that add strength to the solvent, iron. 

At the other extreme, solid solutions are difficult to prepare. To form a solid solution, individual atoms or molecules must mix homogeneously within the solid network. Given that the atoms or molecules in a solid cannot move freely about, such mixing is difficult to achieve. Even if we grind two solids to fine powders and then mix them thoroughly, the resulting mixture will not be a solution, because the mixture will remain heterogeneous at the... 

Now, suppose that we have a solid solution of two (2) elemental solids. Would the point defects be the same, or not An easy way to visualize such point defects is shown in the following diagram, given as 3.1.3. on the next page. It is well to note here that homogeneous lattices usually involve metals or solid solutions of metals (alloys) in contrast to heterogeneous lattices which involve compounds such as ZnS. 

Protons are not the sole species that can be incorporated into the lattices of different host materials. At the beginning of the 1960s, Boris N. Kabanov showed that during cathodic polarization of different metals in alkaline solutions, intercalation of atoms of the corresponding alkali metal is possible. As a result of such an electrochemical intercalation, either homogeneous alloys are formed (solid solutions) or heterogeneous polyphase systems, or even intermetallic compounds, are formed.
