Crystallization parameters
Crystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ). The position… WebKnowledge about the stability of crystal forms and tightly controlled processing conditions are critical to obtain a desired polymorph. Often a simple change in temperature, agitation or solvent composition can …
