Crystalline solids have three-dimensional patterns that contribute to crystal lattice development. In nature, crystalline solids are anisotropic, meaning they have distinct characteristics in various directions. A rigid structure exists in a crystalline solid. WebThe most common method for determining the percent crystallinity of a sample involves comparing the density of the sample to the fully crystalline and fully amorphous densities. The MCL has an Archimedes Density Measurement tool which can be used in conjunction with a regular scale in order to determine the density of a sample.
