| Abstract: | The method of airflow ultrasonic spray thermochemical process was discussed, which can be used
to produce nano-scaled amorphous WO_3-CuO composite powders directly. The hot decomposition process and the
conversion process from amorphous to micro-crystal of the powders were investigated by XRD, TEM and TG-DSC.
The results show that it is feasible to industrially produce nano-scaled WO_3-CuO composite powders on a large scale
by means of airflow ultrasonic spray thermochemical process. The average particle size of WO_3-CuO composite
powders is less than 50 nm,and their shape is spherical. |
