3. Is there a possibility of using piezoceramic actuators at
cryogenic temperatures?
The answer is yes. From down to zero degrees Kelvin, allpiezo
actuators continue to function even though it may appear
counter-intuitive. Since electric fields cannot be changed by
temperature at all and the inter-atomic electric fields are the
basis for the piezoelectric effect, the most common piezoceramics
does decrease due to piezo coupling as temperature drops. Most
importantly the motion of most materials drops to about one-seventh
of that measured at room at liquid helium temperatures.
Company introduction:
Established in 1999, Beijing Cheng-cheng Weiye Science and
Technology Co., Ltd is a professional manufacturer in ultrasonic
transducers, ultrasonic equipment and piezoelectric ceramics.
Notably in 2004, we researched and developed our ultrasonic tubular
transducer equipment into a new product that turns the extreme
inconvenience brought about by pipeline and vacuum cleaning into an
easy task. This product has been widely used in distillation, mix
and mill for various chemical procedures and has received much
praise from our customers.
