klaaskeraamilise

Klaaskeraamiline refers to a material that combines properties of both glass and ceramics. It is manufactured through a process of controlled crystallization, where a glass is induced to form specific crystalline phases within an amorphous glass matrix. This process results in a material with enhanced mechanical strength, thermal shock resistance, and chemical stability compared to conventional glass.

The development of glass-ceramics arose from research into devitrification of glasses. By carefully controlling the composition, cooling rates, and the addition of nucleating agents, manufacturers can dictate the size, shape, and distribution of the crystalline phases. This allows for tailoring the material's properties for a wide range of applications.

Key properties of glass-ceramics include low thermal expansion, which makes them resistant to cracking when subjected to rapid temperature changes. They also exhibit excellent electrical insulation and hardness. The appearance can vary from opaque to transparent depending on the crystalline phases present.

Common applications for glass-ceramics include cookware, where their thermal properties are highly beneficial. They are also used in scientific instruments, telescope mirrors, architectural panels, and even in some medical implants due to their biocompatibility and inertness. The ability to engineer specific properties makes glass-ceramics a versatile material in modern technology.
