The invention provides a rubber ferromagnetic oxide powder and a production process thereof. Iron red and strontium carbonate or barium carbonate are adopted as raw materials, an additive which is favorable to the low-temperature pre-sintering effect improvement and the growth control of crystal grains is preferably added, and a magnetic powder with higher magnetic property and processing property is obtained through the pre-sintering and pulverizing processes, and is suitable to be as a raw material of products such as seals of refrigerator doors, magnetic seals of doors and windows and advertising magnets. The invention has the advantages that the annealing process is not required in the process of preparing the ferromagnetic oxide powder, thereby reducing manufacture cost, lowering energy consumption, and reducing emission.
