Fascinating world of glass and ceramics
From drinking water containers to glasses, from bottles and mirrors to window glass, the dining table is usually made of ubiquitous glass.
It is widely used in science and technology.
There are many kinds of glass and various properties.
New types often appear due to targetsDriving research.
Optical glass is a strategic material used as a lens and prism for the manufacture of Periscope, telescope and telescopefinders, gun-
Science, photography, and instruments like microscope, telescope, camera, projector and optical power station.
Ceramics may refer to clay products in the ordinary sense.
But they made up a big family, from ordinary pottery to advanced pottery.
Ceramics are sometimes combined with other materials to form ceramic composites.
Ceramic composite, capacitor, ceramic fiber, cement, refractory, abrasive, catalytic converter, fiber, optical switch, space shuttle tile, fuel cell, microwave sensor, thermal resistor, dental repair bone some of these applications are implants, missiles, iron-and-electricity assemblies, micro-electronics packages, transistors, and laser amplifiers.
Ceramic is hard.
They are usually resistant to deformation, temperature and corrosion.
The forms of ceramics are alumina, nitrogen Silicon, carbide, zirconium and Sapphire.
Even on a global scale, facilities for Glass and Ceramic Research are limited.
Our country has a rare research center in this field.
Central Institute of glass and ceramics (CGCRI)
Raja S. C. Mullick Road, Kolkata, 196-700032; Phone: 033-24733476; Web site: www. cgcri. res. in.
CGCRIIt has two promotion centersNaroda (Gujarat)and Khurja (UP).
Since 1950, the institute has experienced a tortuous history, interspersed with several milestones.
In addition to regular studies, CGCRI focuses on import substitution.
Optical glass was developed in the early 60 th century.
People in their 70 s have witnessed the development of laser glass and infrared technology.
Red transparent filter, synthetic quartz single crystal, high temperature protective porcelain glaze, aluminum oxide ceramic seal, gasket.
Optical Fiber Communication after 80 s, sol-
Gel Processing of glass and ceramic materials, production of glass fiber-based composites and application of ceramic materials in the field of electronics.
In their 90 s, the focus was on three major areas.
National security, industrial development and social activities.
The institute is now engaged in six sectors: Materials, Minerals and manufacturing, communications and instruments, health care, energy and environment, water technology and rural development.
The Institute\'s clients include several well-known organizations such as the Baba atomic research center, the Mumbai/India Space Research Organization, Bangalore/MoD/steel, and the United Nations Organization for industrial development.
