The direct dependence of the magnetic properties of sintered magnets on the microstructure and phase composition gives special significance to the methods of scanning electron microscopy (SEM) with appropriate software for quantification of visual information (QVI) and X-ray diffraction analysis. The chosen characterization methods are discussed in this paper with a separate presentation of the SEM and X-ray diffraction methods in optimizing the sintering and heat treatment phases in the procedure for obtaining these magnets.

AB  - The  content of the SmCo5 phase, as the carrier of magnetic  properties, was controlled by X-ray diffraction analysis. The content of the SmCo5 phase, as a function of  sintering time and temperature, under constant heat treatment conditions, was observed through the intensity of its most significant  diffraction peak, which corresponds to the (111) plane. By correlating  these parameters  with a mathematical treatment, a mutual dependence was established. A regression dependence  was obtained that showed  that the intensity of the diffraction peak of the (111) plane of the SmCo5 phase depends upon the squares of both  the sintering time and temperature, for given heat treatment conditions. It is possible to optimize the sintering conditions by calculating values of sintering time and temperature for which this dependence has its maximum.

AB  - The dependence of magnetic properties of sintered magnetic materials, demands the quantification of the milling conditions. In this paper the part of the results of the investigation of the phase of milling of SmCo5 powder in investigated technological procedure for production of sintered SmCo5 magnets are presented. The dependence of particle size of SmCo5 powder and oxygen pick-of milling time has been investigated. By X-ray diffraction the occurrence of magnetic SmCo5 phase has been observed. According to experimental data, the optimal milling time has been established, obtaining  the required SmCo5 powder particle size and having the allowed oxygen content.

AB  - Understanding of the thermal stability of intermetallic  SmCo5 powder is essential for designing the working atmosphere in all phases of the technological procedure  in the production of sintered SmCo5 magnets to obtain maximal magnetic properties. The thermal stability of the SmCo5 powder with defined chemical composition and particle size was investigated in the interval from 20 to 900*C. Commercial SmCo5 powder was used in this experiment. The powder was milled in anhydrous toluene in an agate mortar to fine powder of quality used in the production of sintered magnets.  All the experiments were carried out with  powder of an average particle size of 7.23*m, established by SEM. The  thermal stability of the SmCo5 powder in static air atmosphere  was investigated by thermogravimetric analysis  (TGA) using  a DuPont Thermal Analyzer. Investigation of the behavior of  SmCo5 powder during heating was carried out using new samples of  SmCo5 powder for each  of the investigated temperature cycles. It was found by TGA  that up to 200*C, the oxidation of SmCo5 was negligible. X-Ray diffraction of the thermogravimetric experimental residue of the SmCo5 powder, heated at 240*C, yielded only the presence of the SmCo5 phase. By X-ray diffraction different crystal forms were identified depending on the maximal heating temperature. The following phases were identified: Sm2O3, Co, CoO, Co3O4 and SmCoO3. According to TG and X-ray results, for each of the investigated temperatures, the corresponding chemical reactions were established. The experimental data from both the thermal and X-ray investigations confirm that the phases of pressing and aligning the SmCo5 powder, in the process of producing  sintered SmCo5 magnets, may be performed without a protective  atmosphere.
