Quartz

Chettinad Quartz Products Pvt. Ltd was established for producing quartz based products and is presently employed in the production and selling of fused quartz. Plant is located at Kazhipattur Village, Old Mahabalipuram Road , 25kms from Chennai.

RAW MATERIAL
Naturally available quartz is mined by the company and processed for achieving the size fractions required for fusing using in-house technology.

PROCESS
The size reduced quartz is fused to 2000°C by Electric Heating and the Ingot is reduced to various size of requirement.

APPLICATION
Fused Silica is the amorphous type of Silica, completely fused at very high temperature. It is having the lowest thermal expansion coefficient among all the industrial minerals as well as good thermal shock resistance and low thermal conductivity. In addition, it is chemically stable and has high insulation resistance.
Fused Silica is used in various applications according to their characteristics and their usage are outlined below:

CHARACTERISTICS	USAGE
Heat Resistance	Refractory Material
Low Thermal Expansion ratio	Precision Casting
High Purity	Filler for epoxy moulding compound for Semi Conductor Encapsulation
Electric insulability	Filler for paint etc.
