AB  - The influence of the sintering method on the mineral phase transformations and development of the crystalline microstructure of steatite ceramics was investigated. The steatite samples were fabricated from talc and bentonite as low-cost raw materials. Feldspar and barium carbonate, as fluxing agents, were altered in the steatite composition. Dilatometric analysis was applied in the monitoring of the dimensional changes and thereby densification of steatite during the traditional sintering (TS) procedure up to 1200 degrees C. Spark plasma sintering (SPS) method was used under the following sintering conditions: 100 degrees C/min heating rate, uniaxial pressure of 50 MPa; sintering temperature 800 degrees C/1 min or 1000 degrees C/2 min. Crystallinity changes and mineral phase transition during sintering were observed by X-ray diffraction technique. Microstructural visualization of the samples and the spatial arrangements of individual chemical elements were achieved via scanning electron microscopy equipped with the EDS mapping. It was found that SPS sintering facilitated all microstructural changes during high temperature treatment and shifted them to lower temperatures. SPS treatment conducted at 1000 degrees C resulted in maximum densification of the steatite powder compacts and the formation stabilized protoenstatite structure.

AB  - This study provided insights into relations between sintering mechanism and behavior of two types of steatite-based ceramics. Experimental steatite samples were synthesized from low-cost natural raw materials. The sintering was conducted via dilatometer and SPS method. The thermally induced changes in the steatites and its properties were monitored by instrumental analyses: mineral phase transition was investigated via XRD, and the thermal stability was observed using DTA. The investigation highlighted the optimal combinations of the raw materials for production of the steatite ceramics for advanced electrical engineering applications.
