Novel lubricant and application in preparing process of soft magnetic ferrite

The invention relates to a novel lubricant and an application of the novel lubricant in the preparation of soft magnetic ferrite. The novel lubricant comprising following components in percentage by weight: 10 to 25 weight percent of magnesium oxide, 20 to 40 weight percent of silica, 10 to 65 weight percent of stearate and the balance being auxiliary components; the method has the advantages that: 1. the novel lubricant of the invention is simple in manufacturing process, low in cost and good in use effect, and simultaneously possesses of three functions of aided flowing, anti-adhering and lubrication; 2. the novel lubricant of the invention which is applied to the preparation of the soft magnetic ferrite can lower the friction between particle materials and a mold, so as to avoid the difficult demoulding and prolong the service life of the mold; 3. the novel lubricant of the invention which is applied to the preparation of the soft magnetic ferrite can increase the fluidity between particle materials, impro
