What Industries Use X-Ray Diffraction?

Many scientists use X-ray diffraction on a daily basis. This method is known to be quite successful in terms of identifying crystalline material. In addition to this, x-ray diffraction can also provide scientists with information about unit cell dimensions.

Any material that is analyzed is always finely ground. This is because it enables the x-rays to pick up more information about the properties that the material contains. The material is also homogenized and this goes further to ensuring that the bulk composition is found.

Advantages & Disadvantages of XRD and XRF

In Layperson’s Terms

In layperson’s terms, the x-rays are used to detect what the materials contain. However, x-ray diffraction involves a lot more than simply pointing x-rays at a material and hoping the information that’s sent back is correct. Specific angles are used so that a better reading can be taken. Some materials might also be better at revealing their composition than others. However, x-ray diffraction is a very useful tool that can help many different industries to discover exactly what an unknown material contains.

Industries That Use X-Ray Diffraction

X-ray powder diffraction is typically used in a wide range of industries. In fact, XRD tends to be used so that scientists can detect the properties of any unknown crystalline materials. These materials are typically inorganic compounds or minerals.

When it is crucial that unknown solids are identified, it’s usually because the solids are important to studies. These studies might be links to the following industries:

  • Biology
  • Engineering
  • Environmental science
  • Geology
  • Material science

X-ray powder diffraction can prove to be very useful in the above industries. While there are other methods to use, XRD can be many a scientist’s go-to methods.

Alternative applications can include characterizing crystalline materials, determining the dimensions of unit cells, identifying a range of fine materials such as mixed layer clay, and the measurement of a sample purity.

Other Uses For X-Ray Powder Diffraction

Some industries have other uses for x-ray diffraction. These can include using specialty techniques to determine:

Crystal structures – This is typically undertaken by using Rietveld refinement

Modal amounts of specific minerals – This is a form of quantitative analysis

Another use involves characterizing a thin film sample.

The Advantages and Disadvantages of X-Ray Powder Diffraction

Now we’re going to take a look at the advantages and disadvantages of x-ray powder diffraction:

Advantages

– It’s a widely available method

– Interpreting the data is not complicated

– The results can provide a clear answer

– The technique is a powerful one to use

– It often takes less than 20 minutes to show the results

Disadvantages

– You can only use 1/10th of a gram of the material

– The material needs to be ground down into a powder

– There’s always a chance that peak overlay occurs. This can make the reflections worse

– To get better identification you’ll need to use a single phase, homogeneous material

– You will need access to a reference file of many inorganic compounds

– Indexing patterns of some crystal systems can be very difficult

– There is a detection limit with is ~ 2 percent of the sample

As you can see, there are quite a few disadvantages to using x-ray powder diffraction. However, if you don’t have complicated minerals to work with, this method can prove to be very useful.

X-ray powder diffraction can prove to be very useful in the above industries. While there are other methods to use, XRD can be many a scientist’s go-to method. With a little work and with a little practice, you could find that x-ray powder diffraction is your preferred method of detection.
