# XRD d value Calculator

## XRD d value Calculator

#### Calculation Tutorial:

**STEP1:** Open the XRD graph of the material, which is obtained from the instrument.

**STEP2:** Now zoom on the area for which you want to calculate the d value and note down the angle at which peak is shown.

**STEP3:** Now enter the measured Peak Position (i.e. 31.8 degree) in "Peak Position (2 Theta)" column of the calculator. You should get the calculated results of the d value in the "Calculated Result" field.

**NOTE:** Default value of wavelength of LASER is set is 0.15418, which is mostly used in the instruments; and Order of Reflection is 1. You can also change these values as your desire if you want.

**Theory Behind Calculations:**
X-Rays are having wavelength between 0.01nm to 10nm. Hence X-Rays can penetrate inside the crystal structure of any material very easily; and tells us the properties of material while coming out from that material. Which is why X-Ray spectroscopy is very useful technique for characterization of different types of materials.

**Bragg's Law:**

Order of Reflection (n) × Wavelength (λ) = 2 × Interplanar spacing (d) × Sinθ

So, Interplanar spacing can be calculated easily from the formula as:

Interplanar spacing (d) = Order of Reflection (n) × Wavelength (λ) / 2 × Sinθ

very useful thanks

ReplyDeletehow could I calculate theam??

ReplyDeletenL(Wavelenght of inciden beam its almost 0.15418nm)=2dsin(theta)

DeleteI wonder the exact equation about that

ReplyDeletewhat will be effect if d spacing is increasing as concentration of dopinf increases

ReplyDeleteMore likely because of the ionic radii of your dopant greater than the ionic radii of the host.

DeleteVery interesting.Thank you.

ReplyDeletethat is what I really looking for thank you..

ReplyDeletewhy lattice parameters important and what these values tell us while characterization

ReplyDeleteWe do not spend much time thinking. Thank you to the author of this site.

ReplyDeletevery useful......thank you v. much

ReplyDeletethe angle measure in degree or in radian

ReplyDeleteVery good

ReplyDeletevery nice website but if its not too much to ask, it would be great if the website has option of giving the user control of units.
