CEL is Pioneer in manufacturing of different type
of PZT elements since 1976 in India.. CEL manufactures various grades of
Piezo-ceramics elements for low power as well as high power application that is
PZT-5A, PZT-5H, PZT-5J for low power applications and PZT-4, PZT-8 for high
power applications. Piezo ceramics elements can be manufactured in any shape or
size as per the requirement. These are more versatile with physical, chemical
and piezoelectric characteristics able to be tailored to specific applications.
Ceramics can be manufactured in almost any given shape or size.
PZT-5A is used for low power systems and in other applications where is
required high di-electric constant, high voltage sensitivity, volume
resistivity and stability over a wide temperature range. It is most suitable
for making the low power transducers, acoustic sensing elements, flaw detection
probes, Piezo Igniters, medical applications etc.
PZT-4 is used for high power applications where high
electro-mechanical coupling co-efficient and low dielectric losses under high
driving field and a high coercive field are essential. This accepts
more AC driving field without deposing and is ideally suited for high power
electro-acoustic devices, ultrasonic cleaners, high voltage generators, high
power sonar, industrial Equipment etc.
PZT-8 is again used for; high power applications. It is an excellent
choice when the highest electrical drive is required. Due to excellent
dielectric stability and law mechanical loss at high drive condition it is used
for ultrasonic welding, ultrasonic mixing/ dispersion, ultrasonic surgery and
some chemistry etc.
PZT-5J is used for low power applications where high permittivity and
high piezo electric voltage constant required. This material is used in fuses,
hydrophones and other applications that require a combination of high energy
and high voltage output.
PZT 5H is again used for low power applications where extremely high
permittivity, coupling co-efficient and piezoelectric charge coefficient
required. It is an excellent material for field sensors, Level sensors,
Actuator & Accelerometers, Buzzers ultrasonic NDT applications and material
