Raw Material
Qualified raw materials are selected and verified before production.
Technology
Direct-combustion production for submicron spherical powders.
Self-developed production route is designed for spherical metal oxide powders with high purity, rapid reaction control, low energy use, narrow particle distribution, and flexible downstream surface treatment.
Process Flow
Gas
Direct combustion initiates a rapid reaction process.
Droplet
Reaction and cooling conditions shape the forming particles.
Particle
Particles are controlled for morphology, distribution, and top cut.
Spherical Powder
Final collection yields spherical oxide powders for downstream grading and treatment.
Manufacturing Demonstration
The direct-combustion process converts verified raw material into gas, droplets, particles, and finally collected spherical powder through combustion and controlled cooling.
Powder Formation Flow
Raw material passes through combustion, cooling, particle formation, and collection to produce spherical powder.
Direct Combustion
The high-temperature flame demonstrates the rapid reaction environment used to form spherical oxide powder.
Technical Advantages
High Purity
The process avoids introducing additional impurities, allowing product purity to be controlled through raw material purity and supporting 5N+ and low-alpha products.
Low Energy Use
No water use and reaction heat maintaining production without extra energy input.
Fast Reaction
Millisecond-level reaction speed supports rapid formation and process control.
Environmental Profile
Producing no three wastes and no carbon dioxide emissions during production.
Particle Size And Morphology Control
| Material | D50 Capability | Top-Cut / Large Particle Control | Morphology |
|---|---|---|---|
| Spherical alumina | 0.1 to 10 microns controllable | Cut level down to 1 micron for selected products | 100% true spherical target |
| Spherical silica | 0.2 to 2 microns continuously controllable | D100 controlled by grade; large particles above 10 microns can be tightly limited | 100% true spherical target |
