Crystallization point
WebTo characterize the glass transition, the glass transition temperature T g expresses the point at which half of the change in the specific heat capacity is reached. It is also called the glass transition temperature or softening temperature. The thermal glass transition is observed when a melt which cannot crystallize is supercooled. WebCrystallization Point. Since the crystallization point of PC reaches its maximum at approximately 190°C, the molding temperature should be 210°C or higher. From: …

WebNov 26, 2024 · 5.2: Nucleation and crystallization. Living cells consist essentially of an aqueous solution contained within a cell membrane. Thus the soft tissues of many living systems can be described as structured water. The human body for instance, is 50-75 % water. This high proportion of water means that crystallization in the body occurs in two …
