12023-91-5 - Preparation Method
Open Data Verified Data
chemical co-precipitation method: the chloride salt solution of Fe and Sr is mixed in a certain proportion, and then co-precipitated with NaOH and Na2 CO3 alkaline solution. After the precipitate is filtered and washed with water, magnetic powder was obtained by sintering at 925 °c. The magnetic powder was placed in a ball mill and dispersed by ball milling.
