Webcrystal lattice planes, or d (also called d-spacings). θ is the angle between the incident ray and the family of lattice planes, and sin θ is inversely proportional to the distance between successive crystal planes or d-spacings. The direction and spacing of the planes with reference to the unit cell axes are defined by the Miller indices {hkl}. WebThe crystallographic axes are imaginary lines that we can draw within the crystal lattice. These will define a coordinate system within the crystal. For 3-dimensional space lattices …

WebCrystal habit, or morphology, is a crucial attribute of powdered materials that affects the ease with which a pharmaceutical formulation can be pressed into a tablet. In particular, equidimensional crystals are usually preferred in the industry as they have better handling and processing characteristics such as flowability and compatibility.
