CHAPTER 11 PRECISE PARAMETER MEASUREMENTS 11-1 Introduction.

Many applications of x-ray diffraction require precise knowledge of the

applications involve solid solutions; since the

CHAPTER 11 PRECISE PARAMETER MEASUREMENTS 11-1 Introduction.

Many applications of x-ray diffraction require precise knowledge of the

**lattice****parameter**(or parameters) of the material under study. In the main, theseapplications involve solid solutions; since the

**lattice parameter**of a solid solutionvaries with the concentration of the solute, the composition of a given solution

can be determined from a measurement of its

**lattice parameter**. Thermalexpansion coefficients can ...

The constant A, called the drift constant, is a measure of the total systematic error

involved in the determination. Cohen's method of determining

is even more valuable when applied to noncubic substances, since, as we saw in

Sec. 11-2, straightforward graphical extrapolation cannot be used when there is

more than one

direct means of determining these parameters, although the equations are ...
