Thus, the raw materials, i.e. αFe2O3, Mn3O4, and ZnO, in a molar ratio 53:28:19 were mixed in suitable proportions in a steel ball-mill using demineralized water.
Thus, the raw materials aFe2O3, Mn3O4, and ZnO were wet milled, dried and pre-sintered at 800 0C for 1h in air.

Fig.1 The 3 d model diagram of blood pump rotor system Setting the material properties and meshing First set each parts material properties of the blood pump rotor system is needed in the ANSYS Workbench,Because the categories of materials provided by ANSYS is limited.Some specific kind of material parameters need to be created separately,the statics analysis for the blood rotor system need to be taken up.the required material parameters are mainly density, elastic modulus and poisson's ratio.Physical and mechanical properties of each parts material parameters of the blood pump rotor system studied in this paper are shown in table 1,after the set up is completed,The software will automatically based on the components of the three-dimensional entity model to calculate the parameters such as the quality of the parts and the moment of inertia,Provide necessary data foundation for finite element analysis.
