Description:

Glass-ceramicsare mostly produced in two steps: First, a glass is formed by aglass-manufacturing process. The glass is cooled down and is then reheated in asecond step. In this heat treatment the glass partly crystallizes. In mostcases nucleation agents are added to the base composition of the glass-ceramic.These nucleation agents aid and control the crystallization process.Glass-ceramics are fine-grained polycrystalline materials formed when glassesof suitable compositions are heat treated and thus undergo controlledcrystallization to the lower energy, crystalline state. It is important toemphasize a number of points in this statement on glass ceramics.

Technavio’smarket research analyst predicts that the glass ceramics market will grow at amodest CAGR of just over 6% during the forecast period. Glass ceramics hashelped the electronics industry build much smaller and highly efficienttransistors, leading to advances in all types of devices.  Ceramic devices and implants are also verymuch in demand by the medical industry. A number of surgeons prefer to useceramic implants as they are very strong, resistant to corrosion and alsobio-compatible.

Ceramicmaterials are widely used in building projects in commercial and industrialsectors as these materials effectively help reduce sound and are cost-effectivecompared to other materials. The glass ceramics of the CaO-Al2O3-SiO2 systemshow promise as construction materials. They are used for abrasion andchemically resistant parts or floor and wall tile in the chemical, mechanical,construction as well as heavy industries.
