| Abstract |
| The process of hydrothermally growing single crystals of quartz in
high pressure autoclaves at elevated temperatures is described in
brief. Methods ·or cutting and processing of wafers of quartz from
synthetically grown crystals for fabrication of quartz crystal resonator
units are outlined. The principle of operation of quartz crystal units
is explained with the aid of an equivalent LCR circuit and the method
of controlling precisely the frequency of oscillator circuits by a quartz
resonator is elucidated. Extensive applications of quartz in the emerging
electronic era are reviewed, both for analogue and digital circuitry,
and the Indian demand analysed in the perspective of production capacity
of a leading developed country of the world. |
