DEFINITION

Classification: 65/396

Sonic or ultrasonic energy utilized (e.g., homogenizing, dispersing, etc.):

(under subclass 395) Processes wherein the vibratory energy used during any stage of the sol-gel or liquid phase route procedure is sonic or ultrasonic.

(1) Note. Ultrasonic waves vibrate at frequencies beyond the hearing power of human beings (above 20,000 Hz). Sonic frequencies are vibrations which can be heard by the human ear (from about 15 Hz to approximately 20,000 Hz).
