Ultrasonic Spray Pyrolysis For High-Purity Metal Oxide & Ceramic Nanopowders
Jul 16, 2026
Produce Uniform, Low-Agglomeration Nano Powder with Ultrasonic Spray Pyrolysis (USP)
Traditional nanopowder manufacturing methods including sol-gel, solid-state sintering, and high-pressure atomization commonly causeparticle agglomeration, inconsistent particle size, impurity contamination, and low material utilization. These issues greatly limit the performance and batch stability of advanced ceramics, catalysts, and new energy materials.
Ultrasonic Spray Pyrolysis (USP) is an advanced, one-step aerosol synthesis technology designed for producing high-purity, spherical, narrow-distribution metal oxide and ceramic nanopowders. It is widely adopted by global material R&D laboratories and industrial manufacturers for both small-batch trial production and large-scale continuous mass production.
How Ultrasonic Spray Pyrolysis Works?
The entire closed-loop production process is fully automatic and requires no secondary grinding or post-treatment:
Precursor Liquid Preparation Uniformly dissolve metal salts to achieve molecular-level mixing and avoid element segregation in composite powders.
Ultra-Fine Ultrasonic Atomization High-frequency ultrasonic vibration generates uniform micro-droplets without high-pressure impact, ensuring consistent droplet size.
High-Temperature Pyrolysis & Crystallization Droplets are carried into the high-temperature furnace to complete solvent evaporation, pyrolysis, and in-situ crystallization. One droplet forms one spherical particle.
High-Efficiency Powder Collection Equipped with professional electrostatic trapping system, powder recovery rate reaches over 95%.
Core Advantages & Differentiations
Compared with traditional powder synthesis, our USP system provides obvious commercial and technical advantages:
Superior Powder Morphology High sphericity, low agglomeration, narrow particle size distribution (10 nm – 2 μm adjustable). Customizable solid, porous, and hollow structural particles.
Ultra-High Purity Fully enclosed reaction environment without secondary impurity introduction, supporting 99.99% high-purity powder production for semiconductor and medical-grade materials.
High Material Utilization No splash or waste of precious metal precursors. Ideal for platinum, iridium, ruthenium, and rare earth oxide powder production, greatly reducing raw material costs.
Stable Batch Consistency Continuous automatic production with adjustable temperature, gas flow, and liquid feeding parameters. Effectively solves batch fluctuation problems in traditional processes.
Wide Compatibility Supports oxidative, inert, and reducing atmospheres. Compatible with single oxide, multi-component composite ceramics, and lithium battery functional powders.
