Preparation of Cu(OH)_2 nanopowder by the freeze-drying process;

Preparation of nanopowder CuO and Cu(OH)_2 in high intensity ultrasonic field;

Process research on preparation of Cu(OH) 2 nanopowder is developed using ultrasonic technology with chemical precipation method, X-ray diffraction, transmission electromicroscope detection and chemical purity analysis show that the experimental product is non crystalline powder, the grain size is 30~80 nm, the purity is 99.

The Cu(OH) 2 nanometric powders were prepared by a new method of homogeneous precipitation.
