Microstructure and properties of the mullite‒ZrO2(Y2O3)‒Si3N4-composite ceramics sintered in different ways
Keyword(s):
The research objective was to investigate the packing degree, phase composition, microstructure and some other properties of the mullite‒ZrO2composite ceramics with the Si3N4addition sintered in different ways, such as: by the conventional method, by the spark-plasma method, and both in the microwave and solar ovens. The comparative analysis was carried out for the strength properties (these were the ultimate compressing strength and the elasticity modulus) for the ceramic samples which had been sintered by means of the conventional and of the spark-plasma methods. Some reasons for the defect formation in the samples after their sintering in the microwave and solar ovens were mentioned.Ill.8. Ref. 10. Tab. 2.
