Embodiment 1
[0029] 1. Ingredients:
[0030] According to the stoichiometric ratio of each element in the chemical formula, weigh the corresponding oxalic acid H 2 C 2 o 4 2H 2 O2mol, cobalt nitrate Co(NO 3 ) 2 ·6H 2 01mol; Then take respectively surfactant cetyltrimethylammonium bromide and Polyethylene Glycol 1000 of 0.2wt% of the total mass of the above medicines;
[0031] 2. Ball milling:
[0032] The weighed oxalic acid H 2 C 2 o 4 2H 2 O, cobalt nitrate Co(NO 3 ) 2 ·6H 2 O. Cetyltrimethylammonium bromide and polyethylene glycol 1000 are fully mixed; then ball milled (ball-to-material ratio 3:1), absolute ethanol is added during ball milling, and the amount of ethanol added is kept dispersed by the ball milling system After 2 hours of ball milling time, suction filtration was performed, and an appropriate amount of alcohol was added after washing to obtain a precursor solution.
[0033] 3. Spheroidizing spray drying:
[0034] The prepared solution was dried with a sphe...
