Spray Pyrolysis with Ultrasonic Spray Nozzle Technology

Ultrasonic spray pyrolysis is being used in a wide variety of applications from nanoparticle formation to cyrstalline thin film deposition. Ultrasonic spray pyrolysis has been used in the formation of nanoparticles of silver, lithium manganese oxide, zinc sulfide (ZnS), lead oxide (PbO), zirconium dioxide (ZrO2) and yttria-stabalized zirconia (YSZ) ceramics. Additionally, ultrasonic spray pyrolysis is being used in the formation of transparent conductive oxide layers such as indium tin oxide (ITO), zinc oxide (ZnO), aluminum zinc oxide (AZO), and fluorine oxide all common in the solar industry.

Ultrasonic spray nozzle technology used in spray pyrolysis is a viable money saving alternative to chemical vapor deposition (CVD), vacuum deposition and sputtering without compromises to quality. Main advantages of ultrasonic spray pyrolysis are:

• Cost effective method due to high transfer efficiency in thin film formation.
• Substrates with complex geometries can be spray coated.
• Films deposited by ultrasonic spray pyrolysis are reproducible.
• Highly uniform nanoparticle size formation.
• Non clogging nozzles and robust design.

Heated substrates are typically 300-500 degrees C and this environment can cause damage to the inner workings of conventional ultrasonic technology. We offer a high temperature ultrasonic spray nozzle with an extended detachable tip that allows the ultrasonic tip to be inserted into the reaction chamber, while typically isolating or buffering the body of the ultrasonic nozzle from heat. The detachable tip can be swapped out and exchanged for a new tip without having to replace the entire ultrasonic system. This is advantageous to many ultrasonic spray pyrolysis designs, since the ultrasonic nozzle is typically mounted in hard to reach areas.
