lasinlämpötilan

Lasinlämpötila refers to the temperature at which glass transitions from a rigid, glassy state to a more viscous, rubbery state. This transition is not a sharp melting point like that of crystalline solids, but rather a range of temperatures. Above the lasinlämpötila, glass can be molded and shaped, while below it, it becomes brittle. The exact lasinlämpötila varies significantly depending on the specific composition of the glass. For example, silica glass has a very high lasinlämpötila, while borosilicate glass is lower. This property is crucial in glass manufacturing, allowing for processes like blowing, pressing, and drawing glass into various forms. Understanding and controlling the lasinlämpötila is essential for achieving desired glass properties and successful fabrication. It is a key parameter in determining the thermal history and mechanical behavior of glass.
