Lasinlämpötila

Lasinlämpötila refers to the temperature at which glass transitions from a rigid, brittle solid to a more pliable, viscous state. This is not a sharp melting point like that of crystalline solids, but rather a range of temperatures where the material's properties change gradually. The exact lasinlämpötila is dependent on the specific chemical composition of the glass. For example, silica-based glasses, commonly used in windows and bottles, have a high lasinlämpötila, often exceeding 1000 degrees Celsius. Lead-containing glasses, known for their optical clarity and brilliance, tend to have lower lasinlämpötiloja. The lasinlämpötila is a critical parameter in glass manufacturing, influencing processes such as shaping, molding, and annealing. Understanding this temperature range allows manufacturers to effectively work with molten glass and cool it in a controlled manner to prevent internal stresses and ensure the desired mechanical and optical properties in the final product. The transition zone is characterized by increasing molecular mobility within the glass structure.
