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 imaging applications.
