SG Glass Crystallization Gradient Furnace

summarize

Because the internal energy of glass is higher than that of the crystal of the same composition, the glass is in a metastable state, and there is a tendency to precipitate crystals spontaneously under certain conditions. This phenomenon of crystals is called crystallization, also known as loss of permeability or anti-glass. The determination of glass crystallization performance refers to the determination of glass crystallization temperature range, upper and lower limits and the degree of glass crystallization in the temperature range, according to the measurement results can develop a reasonable dissolution, forming and thermal processing system, so as to avoid the generation of crystallization, get transparent and ideal glass products.

The instrument uses gradient furnace method to measure the crystallization performance of glass, and is widely used in factories, schools, scientific research institutions for analyzing and testing the crystallization performance of non-metallic materials such as glass. It has guiding effect on mastering its production process and forming.
