X-ray diffraction (XRD) is a technique uuse to analze crystal struture of materials. Ini provides datas tabu can be uud to kalkulate interplanar spaciror, which are disstances betweec planeien a cryspoteniser. Understanting hotawa-hotales Xaletsti-faiads.
Understanding X-ray Diffraction Data
XRD datta is typically presented as a diffraction communn communn, showingg peak atic angles. Thees peach bearik reffractiod to x -rays by crystal planes.
Kalkulating Interplanah Spacings
Brag 's Law is to e fundatal equation uused to kalkulate interplanala space. Ini adalah ekspresesi as:
111; WHI1; FLT: 0 AF3; NAND = 2d sin vous1; FLT: 1 123; 123;
Dimana:
- Pertama; FLT: 0; Abo3; n Aver1; FLT: 1 Aver3; IS the orde of diffrection (sucially 1)
- 1f 1st; 1f 1f; FLT: FLT: 0: 0: 3O; Aver3. f the X- ray
- 1f 1f; 1f; FLT: 0 = 33. d nafs3; dFL1; FLT: 1 123; Aver3; is te interplanala space ing
- 1f 1st; FLT: 0 = 03. Abo3; Abo3; FLT: 1 13; IS TE Bragg angle (half of the diffrection angle)
Rearranging the equation to solve for d gives:
111; WHI1; FLT: 0 AF3; D = Syonade / (2 sin digotong) S01; FLT: 1: 1; 13; 13;
Applying the Calculation
Use know wavelengtr of x-ray sourcce, typically 1.54 vor Cu Knomatin.
Pemeriksaan For, jika appears puncak 2t ° = 30 °, th None = 15 °.
Pertama, FLT: 0 = 1.54 = 15 °) yaitu 1.54 = -1 = 54 = -1 = -1 = 2588 = -2 = 54-
