How to Calculate Crystallite Size from XRD Data | Scherrer Equation | Origin Pro & Excel

Learn how to calculate crystallite size from XRD data using the Scherrer equation in this step-by-step tutorial. This video walks you through the complete workflow used in real research—from extracting FWHM in Origin Pro to automating crystallite size calculations in Excel. This tutorial is part of InSciLabTech’s “For Researchers by Researchers” initiative, where active scientists share practical, publication-ready methods. 🔬 In this tutorial, you will learn • The theory and assumptions behind the Scherrer equation • Meaning of K, λ, β (FWHM), and θ (Bragg angle) • How to import and plot XRD data in Origin Pro • Identifying and zooming into the main diffraction peak • Performing Gaussian peak fitting to accurately extract FWHM • Converting units correctly (degrees → radians, Å → nm) • Setting up an Excel sheet to calculate crystallite size • Calculating average crystallite size from multiple peaks 📐 Scherrer Equation: D= Kλ/(βcosθ) Where: • D = Crystallite size • K = Shape factor (typically 0.94) • λ = X-ray wavelength (e.g., Cu Kα = 0.15406 nm) • β = FWHM in radians • θ = Bragg angle ⏱ Video Chapters 00:00 Introduction & Initiative 00:16 From XRD Pattern to Crystallite Size 00:37 Scherrer Equation Explained 01:29 Importing XRD Data in Origin Pro 02:06 Selecting & Zooming into the Main Peak 02:16 Gaussian Fit to Determine FWHM 02:47 Extracting FWHM & 2θ 02:58 Setting up the Excel Calculation 03:40 Applying the Scherrer Formula 03:54 Averaging Crystallite Size 04:11 Summary & Community 💻 Software Used • Origin Pro • Microsoft Excel ⚙️ Key Techniques XRD Analysis • FWHM Measurement • Gaussian Peak Fitting • Nanomaterials Characterization 💬 Join Our Research Community Discuss XRD analysis, nanomaterials, and data interpretation with fellow researchers: 👉 https://inscilab.tech/community 🔔 Subscribe for more practical, publication-focused tutorials for researchers.
