Unformatted text preview: Work through the online tutorials to practice indexing points, directions and planes. Examples: Draw , Index planes: That intersect all 3 axes That intersect 2 axes That intersect 1 axis ( ) 3 2 1 ( ) 3 2 2D images of planes The following 2D crosssections of a crystal are looking straight down the zaxis. We are only looking at planes that are parallel to the zaxis You will need to be able to do 3D problems, but 2D is easier to draw and visualize to start with. Crystal Planes Crystal Planes x y (010) d 010 Crystal Planes x y (100) d 100 Crystal Planes x y (110) d 110 Crystal Planes x y (120) d 120 2 2 2 l k h a d hkl + + = dspacing of (hkl) planes in a cubic system XRay Diffraction Reflection Rules for (hkl) planes sin d n = 2 2 2 1 ~ sin ~ l k h d hkl hkl hkl + + = Example XRD Pattern (111) (200) (220) (331) (222)...
