This paper describes the influence of sintering temperature on phase composition and microstructure of paper-derived Ti3AlC2 composites fabricated by spark plasma sintering. The composites were sintered at 100 MPa pressure in the temperature range of 1150-1350 °C. Phase composition and microstructure were analyzed by X-ray diffraction and scanning electron microscopy, respectively. The multiphase structure was observed in the sintered composites consisting of Ti3AlC2, Ti2AlC, TiC and Al2O3 phases. The decomposition of the Ti3AlC2 phase into Ti2AlC and TiC carbide phases was observed with temperature rise. The total content of Ti3AlC2 and Ti2AlC phases was reduced from 84.5 vol.% (1150 °C) to 69.5 vol.% (1350 °C). The density of composites affected by both the content of TiC phase and changes in porosity.

Summarizing the work of nearly a decade of research on spark plasma sintering (SPS), a review is given on the specificities and key factors to be considered in SPS of ceramic materials, based on the authors’ own research. Alumina is used primarily as a model material throughout the review. Intrinsic inhomogeneities linked to SPS and operational parameters, which depend on the generation of atomistic scale defects, are discussed in detail to explain regularly observed inhomogeneities reported in literature. Adopting an engineering approach to overcome these inherent issues, a successful processing path is laid out towards the mastering of SPS in a wide range of research and industrial settings.

The results of the study of the spark plasma sintering of SmS-based ceramics have been presented. The dependence of the microstructure and phase composition of ceramics on the temperature of spark plasma sintering was studied by using SEM, EDX and XRD. It is shown that, at a sintering temperature of 1200 ° C, dense, non-porous ceramics are formed and the phase composition of the sintered ceramics is close to that of the initial powder.

Powder Metallurgy Methods

Spark Plasma Sintering (SPS), also known as pulsed electric current sintering (PECS) or field assisted sintering technology (FAST), belongs to a class of powder metallurgy methods. Investigations of the effect of thermal, electric and electromagnetic fields arising under the conditions of spark plasma sintering of ceramic materials on their final characteristics are of important fundamental scientific significance. In this regard, the work investigated the effect of the IPA temperature on the structure, composition and magnetic properties of hematite α-Fe2O3 of high purity 99.995%. Changes in the structure and composition of ceramic specimens under SPS conditions in the temperature range 800-1000°C are described by scanning electron microscopy and X-ray phase analysis. The magnetic properties are studied and the regularities of changes of the magnetization (Ms) and coercive force (Hc) under the influence of an external magnetic field for ceramic samples are determined depending on the temperature of the SPS. These results can be considered as initial study of the process of consolidation of materials with weak ferromagnetism under conditions of spark plasma sintering.

Short Time

Spark plasma sintering (SPS) is a promising method to obtain robust silicon carbide (SiC) joint at a relatively low temperature within a short time. In this work, the joint of SiC ceramics was prepared with TiH2, Si and C mixture powders by SPS from 1150 to 1450 °C for 10 min. The microstructure of SiC joints was observed by scanning electron microscopy (SEM), and the phase composition of the interlayer was determined by x-ray diffraction (XRD) and energy dispersive spectrometer (EDS). The mechanical properties of SiC joints were evaluated by the single lap shear test. The results showed that the microstructure and phase composition of the joints depended on the joining temperature. A dense joint could be obtained above 1250 °C. Ti3SiC2 and TixCy were found in all joints. Also, the decomposition of Ti3SiC2 occurred in the 1450 °C joint. The highest shear strength of 80.5 ± 7.4 MPa was obtained in the 1350 °C joint. The fracture occurred within the joining interlayer and SiC ceramics during shear test, except for the 1150 °C joint, which existed obvious cavities in the joint.

AbstractHydroxyapatite was synthesized via sol-gel and solid-state reaction. Both compounds were investigated using high-temperature X-ray diffraction and differential scanning calorimetry. For sol-gel hydroxyapatite, we observed a phase transition, confirmed by character of changing of unit-cell parameters, thermal expansion coefficients and endothermic effect on DTA curve. In the process of obtaining ceramics using spark-plasma sintering both compounds manifested an unexpected shrinkage rate. All effects were explained on the basis of changings in crystal structure during distortion polymorphic transition.
