Crystalline vs amorphous examples
WebSome examples of amorphous solids are glass, rubber, pitch, many plastic etc. Quartz is an example of a crystalline solid which has regular order of the arrangement of SiO 4 tetrahedra. If quartz is melted and the melt is cooled rapidly enough to avoid crystallization an amorphous solid called glass is obtained. WebExamples of Amorphous and Crystalline Polymers. Although 100 percent and 0 percent crystallinity are rare, some polymers fall close to either extreme. Those that tend toward high crystallinity are rigid, have high …
